Profound variation in dihydropyrimidine dehydrogenase activity in human blood cells: major implications for the detection of partly deficient patients. (1/1434)

Dihydropyrimidine dehydrogenase (DPD) is responsible for the breakdown of the widely used antineoplastic agent 5-fluorouracil (5FU), thereby limiting the efficacy of the therapy. To identify patients suffering from a complete or partial DPD deficiency, the activity of DPD is usually determined in peripheral blood mononuclear cells (PBM cells). In this study, we demonstrated that the highest activity of DPD was found in monocytes followed by that of lymphocytes, granulocytes and platelets, whereas no significant activity of DPD could be detected in erythrocytes. The activity of DPD in PBM cells proved to be intermediate compared with the DPD activity observed in monocytes and lymphocytes. The mean percentage of monocytes in the PBM cells obtained from cancer patients proved to be significantly higher than that observed in PBM cells obtained from healthy volunteers. Moreover, a profound positive correlation was observed between the DPD activity of PBM cells and the percentage of monocytes, thus introducing a large inter- and intrapatient variability in the activity of DPD and hindering the detection of patients with a partial DPD deficiency.  (+info)

Interaction of Borrelia burgdorferi with peripheral blood fibrocytes, antigen-presenting cells with the potential for connective tissue targeting. (2/1434)

BACKGROUND: Borrelia Burgdorferi has a predilection for collagenous tissue and can interact with fibronectin and cellular collagens. While the molecular mechanisms of how B. burgdorferi targets connective tissues and causes arthritis are not understood, the spirochetes can bind to a number of different cell types, including fibroblasts. A novel circulating fibroblast-like cell called the peripheral blood fibrocyte has recently been described. Fibrocytes express collagen types I and III as well as fibronectin. Besides playing a role in wound healing, fibrocytes have the potential to target to connective tissue and the functional capacity to recruit, activate, and present antigen to CD4(+) T cells. MATERIALS AND METHODS: Rhesus monkey fibrocytes were isolated and characterized by flow cytometry. B. burgdorferi were incubated with human or monkey fibrocyte cultures in vitro and the cellular interactions analyzed by light and electron microscopy. The two strains of B. burgdorferi studied included JD1, which is highly pathogenic for monkeys, and M297, which lacks the cell surface OspA and OspB proteins. RESULTS: In this study, we demonstrate that B. burgdorferi binds to both human and monkey (rhesus) fibrocytes in vitro. This process does not require OspA or OspB. In addition, the spirochetes are not phagocytosed but are taken into deep recesses of the cell membrane, a process that may protect them from the immune system. CONCLUSIONS: This interaction between B. burgdorferi and peripheral blood fibrocytes provides a potential explanation for the targeting of spirochetes to joint connective tissue and may contribute to the inflammatory process in Lyme arthritis.  (+info)

Quantification of T-cell progenitors during ontogeny: thymus colonization depends on blood delivery of progenitors. (3/1434)

An in vivo thymus reconstitution assay based on intrathymic injection of hematopoietic progenitors into irradiated chicks was used to determine the number of T-cell progenitors in peripheral blood, paraaortic foci, bone marrow (BM), and spleen during ontogeny. This study allowed us to analyze the regulation of thymus colonization occurring in three waves during embryogenesis. It confirmed that progenitors of the first wave of thymus colonization originate from the paraaortic foci, whereas progenitors of the second and the third waves originate from the BM. The analysis of the number of T-cell progenitors indicates that each wave of thymus colonization is correlated with a peak number of T-cell progenitors in peripheral blood, whereas they are almost absent during the periods defined as refractory for colonization. Moreover, injection of T-cell progenitors into the blood circulation showed that they homed into the thymus without delay during the refractory periods. Thus, thymus colonization kinetics depend mainly on the blood delivery of T-cell progenitors during embryogenesis.  (+info)

Expression of IkappaBalpha in the nucleus of human peripheral blood T lymphocytes. (4/1434)

According to current models the inhibitory capacity of I(kappa)B(alpha) would be mediated through the retention of Rel/NF-kappaB proteins in the cytosol. However, I(kappa)B(alpha) has also been detected in the nucleus of cell lines and when overexpressed by transient transfection. To gain better insight into the potential role of nuclear I(kappa)B(alpha) in a physiological context we have analysed its presence in the nucleus of human peripheral blood T lymphocytes (PBL). We demonstrate the nuclear localization of I(kappa)B(alpha) in PBL by different techniques: Western blot, indirect immunofluorescence and electron microscopy. Low levels of nuclear I(kappa)B(alpha) were detected in resting cells whereas a superinduction was obtained after PMA activation. The nuclear pool of I(kappa)B(alpha) showed a higher stability than cytosolic I(kappa)B(alpha) and was partially independent of the resynthesis of the protein. Unexpectedly, the presence of nuclear I(kappa)B(alpha) did not inhibit NF-kappaB binding to DNA and this phenomenon was not due to the presence of IkappaBbeta at the nuclear level. Immunoprecipitation experiments failed to demonstrate an association between nuclear I(kappa)B(alpha) and NF-kappaB proteins. Our results demonstrate that in resting and PMA-activated human PBL, I(kappa)B(alpha) is present in the nucleus in an apparently inactive form unable to disrupt NF-kappaB binding from DNA.  (+info)

Sensitive detection of squamous cells in bone marrow and blood of head and neck cancer patients by E48 reverse transcriptase-polymerase chain reaction. (5/1434)

In previous studies, we described the selective reactivity of monoclonal antibody E48 with normal squamous and transitional epithelia and their malignant counterparts and the capacity of monoclonal antibody E48 for selective tumor targeting in head and neck cancer patients. Cloning of the E48 encoding cDNA and elucidation of the gene structure enabled the selection of an intron-spanning primer set for the detection of circulating tumor cells in blood and bone marrow of head and neck cancer patients. Extensive optimizations led to a reproducible reverse transcriptase-PCR assay with an internal standard for RNA quality control and an external standard for sensitivity control. In reconstruction experiments, we were able to reach a reproducible sensitivity of one single tumor cell per 7 ml of blood (2 x 10(7) nucleated cells). When applying this method to patient material, we were able to detect positive signal in 35% of the bone marrow samples (0 of 2 stage II, 0 of 4 stage III, 4 of 11 stage IV, and 4 of 6 recurrences) and 10% of the blood samples (2 of 21) of patients with squamous cell carcinoma of the head and neck. The specificity of the method was demonstrated on 29 blood and bone marrow samples of noncancer controls, which were all negative. Our study shows the feasibility of E48 reverse transcriptase-PCR for the detection of squamous cells in nonsquamous tissues.  (+info)

Bacterial peptidoglycan polysaccharides in sterile human spleen induce proinflammatory cytokine production by human blood cells. (6/1434)

Peptidoglycan (PG) is the major component of the cell wall of gram-positive bacteria. In vitro, PG isolated from conventional bacterial cultures can induce secretion of proinflammatory cytokines by human monocytes, indicating that PG may be involved in immune responses against infections by gram-positive bacteria. To investigate the biologic activity of PG in human tissues, an improved method was developed to isolate significant amounts of PG from sterile human spleen tissue. Biochemical analysis demonstrated that PG isolated from human spleen is largely intact. Human whole blood cell cultures were able to produce the proinflammatory cytokines tumor necrosis factor-alpha and interleukin-1 and -6 after stimulation with PG isolated from human spleen. Cytokine induction was not sensitive to inhibition by polymyxin B, in contrast to lipopolysaccharide. Collectively, the data show that intact PG in sterile human tissue is biologically active and may induce local proinflammatory cytokine production.  (+info)

Selective tetraspan-integrin complexes (CD81/alpha4beta1, CD151/alpha3beta1, CD151/alpha6beta1) under conditions disrupting tetraspan interactions. (7/1434)

The tetraspans are molecules with four transmembrane domains which are engaged in multimolecular complexes (the tetraspan web) containing a subset of beta1 integrins (in particular alpha3beta1, alpha4beta1 and alpha6beta1), MHC antigens and several unidentified molecules. The molecules associated with tetraspans are readily detected after immunoprecipitation performed in mild detergents such as Brij 97 or CHAPS. In this study we show that another classical mild detergent, digitonin, dissociated most of these associated molecules, including integrins, from the tetraspans CD9, CD37, CD53, CD63, CD82, Co-029, Talla-1 and NAG-2. In contrast, reciprocal immunoprecipitations from various cell lines demonstrated that two other tetraspans, CD81 and CD151, formed complexes with integrins not disrupted by digitonin. These complexes were CD81/alpha4beta1, CD151/alpha3beta1 and CD151/alpha6beta1. Furthermore, a new anti-CD151 monoclonal antibody (mAb), TS151r, was shown to have a restricted pattern of expression, inversely related to the sum of the levels of expression of alpha6beta1 and alpha3beta1. This mAb was unable to co-precipitate integrins in digitonin, suggesting that its epitope is blocked by the association with integrins. Indeed, the binding of TS151r to the cell surface was quantitatively diminished following alpha3beta1 overexpression. Altogether, these data suggest that, among tetraspans, CD81 interacts directly with the integrin alpha4beta1, and CD151 interacts directly with integrins alpha3beta1 and alpha6beta1. Because all tetraspan-tetraspan associations are disrupted by digitonin, it is likely that the other tetraspans interact indirectly with integrins, through interactions with CD81 or CD151.  (+info)

Mouse NKR-P1B, a novel NK1.1 antigen with inhibitory function. (8/1434)

The mouse NK1.1 Ag originally defined as NK cell receptor (NKR)-P1C (CD161) mediates NK cell activation. Here, we show that another member of the mouse CD161 family, NKR-P1B, represents a novel NK1.1 Ag. In contrast to NKR-P1C, which functions as an activating receptor, NKR-P1B inhibits NK cell activation. Association of NKR-P1B with Src homology 2-containing protein tyrosine phosphatase-1 provides a molecular mechanism for this inhibition. The existence of these two NK1.1 Ags with opposite functions suggests a potential role for NKR-P1 molecules, such as those of the Ly-49 gene family, in regulating NK cell function.  (+info)

The health benefits of natural products have long been recognized. Consumption of dietary compounds such as supplements provides an alternative source of natural products to those obtained from the diet. There is a growing concern regarding the possible side effects of using different food supplements simultaneously, since their possible interactions are less known. For the first time, we have tested genotoxic and antigenotoxic effects of Biochaga, in combination with dihydroquercetin. No genotoxic effect on whole blood cells was observed within individual treatment of Biochaga (250 μ g/mL, 500 μ g/mL and 1000 μ g/mL) and dihydroquercetin (100 μ g/mL, 250 μ g/mL and 500 μ g/mL), nor in combination. Afterwards, antigenotoxic potency of both supplements against hydrogen peroxide- (H 2 O 2 -) induced DNA damage to whole blood cells (WBC) was assessed, using the comet assay. Biochaga and dihydroquercetin displayed a strong potential to attenuate H 2 O 2 -induced damage on DNA in cells at ...

Acute rejection is a major complication of solid organ transplantation that prevents the long-term assimilation of the allograft. Various populations of lymphocytes are principal mediators of this process, infiltrating graft tissues and driving cell-mediated cytotoxicity. Understanding the lymphocyte-specific biology associated with rejection is therefore critical. Measuring genome-wide changes in transcript abundance in peripheral whole blood cells can deliver a comprehensive view of the status of the immune system. The heterogeneous nature of the tissue significantly affects the sensitivity and interpretability of traditional analyses, however. Experimental separation of cell types is an obvious solution, but is often impractical and, more worrying, may affect expression, leading to spurious results. Statistical deconvolution of the cell type-specific signal is an attractive alternative, but existing approaches still present some challenges, particularly in a clinical research setting. ...
OBJECTIVES: Carbon monoxide (CO) is a colorless and odorless gas responsible for poisoning mortality and morbidity in the United States. At this time, there is no reliable method to predict the severity of poisoning or clinical prognosis following CO exposure. Whole blood cells, such as peripheral blood mononuclear cells (PBMCs) and platelets, have been explored for their potential use to act as sensitive biomarkers for mitochondrial dysfunction which may have a role in CO poisoning. DESIGN: The objective of this study was to measure mitochondrial respiration using intact cells obtained from patients exposed to CO as a potential biomarker for mitochondrial inhibition with results that can be obtained in a time frame useful for guiding clinical care ...
Fulphila is used to reduce the duration of neutropenia (low white blood cell count ) and the occurrence of febrile neutropenia (low white blood cell count with concomitant fever) which may be due to the use of cytotoxic chemotherapy (drugs that destroy fast-growing cells). The white blood cells are important because they help your body fight infection. These blood cells are very sensitive to chemotherapy and this treatment can lead to a decrease in their number in the body. About the number of white blood cells drops to a low level, there may not be enough left in the body to fight bacteria, and then you may become more susceptible to infection..

What are white blood cell disorders? White blood cells (WBCs), also referred to as leukocytes, are the cells of the immune system that protect the body against infectious disease, allergens, and other foreign invaders. White blood cells are produced in the bone marrow or blood factory. There are several types of WBCs in the blood, each with a specific job and function. Disease states and disorders occur when either too few or too many white blood cells are present. The most common forms of this condition are:
Stem cell scientists led by Mick Bhatia from the McMaster University have successfully converted adult human blood cells into neural cells.. The team directly converted adult human blood cells to both central nervous system (brain and spinal cord) neurons as well as neurons in the peripheral nervous system (rest of the body) that are responsible for pain, temperature and itch perception.. This means that how a persons nervous system cells react and respond to stimuli can be determined from his blood.. Now we can take blood samples and make the main cell types of neurological systems - the central nervous system and the peripheral nervous system - in a dish that is specialised for each patient. Nobody has ever done this with adult blood. Ever, explained Bhatia, director of the McMaster Stem Cell and Cancer Research Institute..

Learning all of these different names and the function of each cell type takes a bit of effort, but you can understand scientific articles a lot better once you get it all figured out! Heres a quick summary to help you get all of the different cell types organized in your brain.. All white blood cells are known officially as leukocytes. White blood cells are not like normal cells in the body -- they actually act like independent, living single-cell organisms able to move and capture things on their own. White blood cells behave very much like amoeba in their movements and are able to engulf other cells and bacteria. Many white blood cells cannot divide and reproduce on their own, but instead have a factory somewhere in the body that produces them. That factory is the bone marrow.. ...

An intracellular complement system (ICS) has recently been described in immune and nonimmune human cells. This system can be activated in a convertase-independent manner from intracellular stores of the complement component C3. The source of these stores has not been rigorously investigated. In the present study, Western blotting identified a band corresponding to C3 in freshly isolated human peripheral blood cells that was absent in corresponding cell lines. One difference between native cells and cell lines was the time absent from a fluid-phase complement source; therefore, we hypothesized that loading C3 from plasma was a route of establishing intracellular C3 stores. We found that many types of human cells specifically internalized C3(H2O), the hydrolytic product of C3, and not native C3, from the extracellular milieu. Uptake was rapid, saturable, and sensitive to competition with unlabeled C3(H2O), indicating a specific mechanism of loading. Under steady-state conditions, approximately 80% ...

The researchers want to find out more about the mechanics of blood cells and gain a detailed understanding of the forces which move and shape cells. In the case of red cells in particular, it is important to know precisely about their properties and their internal forces - because they are unusually soft and elastic and change their shape in order to be able to pass through the sometimes minute blood vessels in our body. It is precisely because blood cells are normally so soft that, in previous studies, physicists measured large thermal fluctuations at the outer membrane of the cells. These natural movements of molecules are defined by the ambient temperature. In other words, the cell membrane of the blood cells moves because molecules in the vicinity jog it. Under the microscope, this makes the blood cells appear to be wriggling. Although this explains why blood cells move, it does not address the question of possible internal forces being a contributory factor. So the research team led by Timo ...

The human blood cell production system usually remains extremely robust, in terms of cell number or function, with little signs of decline in old age. To achieve robustness, circulating blood cells rely on a formidable production machinery, the hematopoietic system, located in the bone marrow. All circulating blood cells---red blood cells, white blood cells and platelets---are renewed on a daily basis. The hematopoietic system produces an estimated 1e12 cells per day. This is a significant fraction of the 3.7e13 cells in an adult. Robustness is partly due to the short time scales at which cell populations are able to return to equilibrium, combined with large cell numbers and renewal rates. White blood cells (WBCs), among which neutrophils are most prevalent, are the bodys first line, innate immune system. Upon infection, WBCs are mobilized from the bone marrow, to increase their number in circulation and fight off pathogen within hours. The 26 billion circulating neutrophils in human have a

CCR5 is the center of the research because this gene encodes a protein that HIV uses to enter human blood cells. Other studies have revealed that people who have a mutation in the CCR5 gene are protected against that virus.. The scientist Jiankui altered the genes of seven embryos in an in vitro fertilization clinic (IVF), causing a mutation called Δ32, where carriers have two copies of the CCR5 gene instead of one.. The goal was to make the children that emerged from these embryos resistant to HIV, and this is how the Nana and Lulu twins were born from this experiment.. You may be wondering: if this seems so beneficial, what is the problem? Although the alteration of genes may have advantages, the consequences are not yet fully known, and these could be very serious. Among them, there could be unwanted and unknown mutations in people with modified DNA.. An article published by the journal Nature explains that people who have the Δ32 mutation are 20% less likely to live up to 76 years, ...

The NIH conclusions were not correct, however. Hickey and Roberts examined their experiments and found them to be full of errors. For example, the researchers had given a dose of vitamin C, waited until it had been excreted and then measured blood levels. Using this procedure, they found that increasing the dose did not greatly increase the blood levels. Instead of realising that this was because the dose had been excreted, the NIH claimed it was because the body was saturated, so higher doses were redundant. They then used white blood cells as a model for normal cells, to see how they absorbed vitamin C from their surroundings. These white blood cells are specialised to absorb vitamin C, even when supplies are low. If other body cells were similar to white blood cells, we would normally have a reserve of 40 grams in our bodies. In this case, given the proposed RDA of 200mg, it would take 2-3 years to fill a depleted body. This is demonstrably incorrect: the classic example is that James Linds ...

Prediction of left ventricular (LV) remodeling after acute myocardial infarction (MI) is clinically important and would benefit from the discovery of new biomarkers. Blood samples were obtained upon admission in patients with acute ST-elevation MI who underwent primary percutaneous coronary intervention. Messenger RNA was extracted from whole blood cells. LV function was evaluated by echocardiography at 4-months. In a test cohort of 32 MI patients, integrated analysis of microarrays with a network of protein-protein interactions identified subgroups of genes which predicted LV dysfunction (ejection fraction ≤ 40%) with areas under the receiver operating characteristic curve (AUC) above 0.80. Candidate genes included transforming growth factor beta receptor 1 (TGFBR1). In a validation cohort of 115 MI patients, TGBFR1 was up-regulated in patients with LV dysfunction (P | 0.001) and was associated with LV function at 4-months (P = 0.003). TGFBR1 predicted LV function with an AUC of 0.72, while peak
Research in industrial workers and professionals exposed to formaldehyde suggests that occupational exposure to this important chemical is associated with increased risk for myeloid leukemia. However, there is still uncertainty about the biologic plausibility of the association because of questions regarding the ability of formaldehyde, which is extremely reactive, to directly or indirectly cause toxicity to the bone marrow. There have been several relatively small studies of the impact of occupational formaldehyde exposure on peripheral blood cells that found some evidence that peripheral blood cells of the myeloid lineage (i.e., granulocytes, platelets) were significantly decreased in exposed workers. We propose to follow-up these findings in a relatively large study population in China. We will study hematologic parameters in 240 higher exposed workers (,1 ppm), 240 workers exposed to lower levels of formaldehyde (0.3 to 1 ppm), and a group of 240 unexposed controls frequency-matched to ...
Red blood cells, or erythrocytes, travel through circulating blood carrying oxygen to body tissues and organs while removing waste. These blood cells make up the largest part of the blood system.. As the red blood cells in blood travel through the lungs, oxygen molecules from the lungs attach to the hemoglobin, a protein in the blood cells that contains iron. The oxygen is then released to tissues and organs, and the hemoglobin bonds with carbon dioxide and other waste gases. These waste products are transported away and removed as blood continues to circulate.. Millions of red blood cells are contained in a single drop of blood. Red blood cells are constantly being produced in the bone marrow to replenish those that gradually wear out and die. The average life of a red blood cell is about 120 days.. A significant decrease in the number of red blood cells causes anemia and shortness of breath. ...
Blood cells are made in the bone marrow. The bone marrow is the spongy material in the center of the bones that produces all types of blood cells.. There are other organs and systems in our bodies that help regulate blood cells. The lymph nodes, spleen, and liver help regulate the production, destruction, and differentiation (developing a specific function) of cells. The production and development of new cells in the bone marrow is a process called hematopoiesis.. Blood cells formed in the bone marrow start out as a stem cell. A stem cell (or hematopoietic stem cell) is the initial phase of all blood cells. As the stem cell matures, several distinct cells evolve, such as the red blood cells, white blood cells, and platelets. Immature blood cells are also called blasts. Some blasts stay in the marrow to mature and others travel to other parts of the body to develop into mature, functioning blood cells.. ...

Another goal of BLUEPRINT will be to investigate epigenetic variation between individuals by studying two cell types from at least 200 healthy donors, while a third cell type from the same donors will be analyzed by a Canadian IHEC project ( These donors will be subjected to complete genome sequencing by the Wellcome Trust Sanger Institute, as well as part of the UK10K project ( allowing epigenetic and genetic variation to be correlated. As the epigenome is expected to be more plastic and influenced by many environmental factors, including diet, age and environmental exposure,14 a likely finding will be that the epigenomes are more variable between individuals then their genomes. Moreover, it will reveal the natural epigenetic variation between cell types from different individuals and to what extent this variation is influenced by variations in the genome sequence. In addition, it will be extremely ...
Red blood cells play a very important role in carrying oxygen for the whole body and use a particular protein called hemoglobin. Anemia means that the amount of red blood cells or the amount of hemoglobin is lower than the normal. As the output of blood cells is either very less or there has been an increased loss of blood cells which causes the deficiency. Red blood cells are manufactured in the bone marrow with the life expectancy of four months. The concoction to produce red blood cells is iron, vitamin B12 and folic acid and the lack of participation by any of those leads to anemia.. This lack or deficiency of red blood cells makes them work harder and exert more to get the required amount of oxygen around the body. This is a chain reaction, as the blood cells are less the provision of oxygen to the body is less. This makes lungs and heart work harder to get oxygen into the blood and due to which there is difficulty in breathing. Heavy exercise, climbing stairs, which are some of the very ...
Leukemia is a cancer of the blood cells. There are many different types of leukemia, depending upon which specific blood cells are affected. Each leukemia has different disease characteristics and therefore different treatment options. Several clinical diagnostic tests are utilized in order to determine the type and extent of leukemia. In order to better understand leukemia and its treatment, a basic understanding of normal blood cell production is useful.. Normal blood is made up of fluid called plasma and three main types of blood cells. Plasma is mainly water, but contains minerals, proteins and antibodies. The three major blood cell types are white cells, red cells and platelets. Each type of blood cell has a specific function. White blood cells, also called leukocytes, help the body fight infections and other diseases. Red blood cells, also called erythrocytes, make up half the bloods total volume. They contain hemoglobin, which picks up oxygen from the lungs and carries it to the bodys ...

Red blood cells are stored in blood collection centres for blood transfusion; however, some of red blood cells are discarded due to the poor quality after storage for a period of time because the poor quality of the red blood cells will cause health problems in individuals after transfusion. In this project, we are going to test new compounds derived from natural anti-freezing proteins by a Canada-based biotech company Sirona for better storage of red blood cells. Hopefully, we will find that these new compounds can improve the quality of the red blood cells after storage.. ...

Red blood cells are the most abundant anucleate cell type in the human body, Yet little is known about them apart from their vital role in transporting oxygen to organs and tissues. Almost all of us know that blood vessels signal bone marrow for red blood cell production in case of low volume of blood or decreased number of red blood cells. But a research team, led by a scientist at Weill Cornell Medical College, has discovered that red blood cells perform a second vital function: angiogenesis, the creation of new blood vessels from those that already exist. These investigators showed that red blood cells supply a lipid that is known to regulate angiogenesis, sphingosine-1-phosphate (S1P). Angiogenesis is necessary for growth, repair and regenerative processes that require increased blood flow and oxygenation of tissues. Given its role in creating new blood vessels, scientists recognize S1P as vital to human health - and a player in some diseases, such as cancer. And although S1P is known to be ...
Raised liver enzymes and low white blood cells are two separate conditions that have several mild to severe causes and indications. Both conditions can manifest from the same disease or its treatments. Your physician will typically address each issue separately while trying to determine the underlying factor.
Each element of blood performs a special function in the body. The main elements of blood include two types of cells, platelets, and plasma. Red blood cells carry oxygen from the lungs to all other body tissues. In the tissues, these cells pick up carbon dioxide that is carried back to the lungs to be released from the body. White blood cells are one of the bodys defenses against disease. Some of these cells travel throughout the body and destroy bacteria, some produce antibodies against bacteria and viruses, and others help fight malignant diseases. Platelets are blood elements that lead to the formation of blood clots in response to injury. Plasma is a yellowish fluid composed of about 92 percent water and 7 percent vital proteins, such as albumin, gamma globulin, anti-hemophiliac factor, and other clotting factors. The remainder consists of mineral salts, sugars, fats, hormones, and vitamins. Red blood cells, white blood cells, and platelets account for about 45 percent of the volume of ...

The second line of defence is also a non-specific response (i.e. the response is the same for any pathogen). It is a 3-pronged attack on any microbes that have survived the first line of defence... Attack no 1: Inflammation (Yes, this is good!) Inflammation happens because cells damaged by invading pathogens and particular white blood cells release alarm chemicals which makes blood vessels enlarge (vasodilate) and the capillaries more leaky. This means that: More blood is coming to the site of the infection, bringing with it more white blood cells of the immune system 2. Then, the white blood cells are let out of the blood capillaries and into the affected tissue. This extra blood makes the area red (as more blood means that the area looks red) and swollen (more blood and liquid leaving the blood and entering the tissue fluid surrounding the body cells). The area will also become hot (as the extra blood is also carrying heat with it) and painful (because the tissues will be swollen with the

Well, after all my midnight rantings and loading of Family Guy DVDs into my backpack, it turns out my counts were too low to start round 3 of chemo today. Its a normal thing, to have the counts go low, so the docs said theres nothing to worry about. On the plus side, they also mentioned that the butt bump has shrunk (on CT scan) to a measly 8 mm by 3 mm. They werent even able to see the lung nodules, but this was also a low-resolution CT, so well have to wait for a better scan in the future to be sure about those. My white blood cell count was the culprit this time around - platelets and red blood cells are good. Probably this will mean more shots of neupogen after the next round (thats the injection I have to take every night after a cycle to get my counts up). The other plus is I get another week of semi-normal life before starting again (yay ...
Fasting diets have always been controversial and that IS why the reasons why people choose to fast in the first place. While some are doing it purely for religious reasons, others do it to lose weight in a short time. One thing is certain, most nutritionists do not approve of this type of diet. However, one recent study, which is published extensively in the media the past few weeks has proved that only three days of fasting can restore your immune system, which will then work even better, because it stimulates stem cells to produce more white blood cells. As you probably already know, the white blood cells are essential for the proper functioning of the immune system, given that fight infection and disease wherever they occur. The study found that those with weakened immune systems can benefit from fasting, because it will rejuvenate natural defense mechanism for a few days. This study shows that even older people can benefit from three days of fasting, when properly implemented. Renowned ...
If you have a weak immune system, you are prone to various illnesses and diseases due to damage caused by the free radicals.

In a nutshell, white blood cells are our defenders against disease. What most people dont know is that within WBC, there are three different types of WBC of which the neutrophil is the most prevalent. Think of these guys like the Marines; theyre first into battle and do most of the work when waging war against infection and disease. A normal healthy person will have an average neutrophil count (ANC) 1500 or more of these guys in a blood sample. If youre slightly ill, you might have anywhere from 1000 to 1500. If youre really feeling a bit under the weather, youve got about 500 to 1000. Less than 500 and the next strain of bacteria could kill you. Haydens current count is 120. Basically, if he were to get an infection he has no defense against it and could die in a mere matter of hours. Even the natural bacteria on his skin could cause complications ...

  • Blood is comprised of red blood cells, platelets, and various white blood cells. (
  • Replace your hemophobia and learn to love your plasma, platelets and all the wonderful cells pulsing through your veins. (
  • Platelets, or thrombocytes, are the smallest cells (or cell fragments) in the blood. (
  • The primary purpose of platelets is to prevent bleeding by creating blood clots, and the average person has between 150,000 to 400,000 platelets in every drop (or microliter) of blood. (
  • Those immature cells then divide again, mature even more, and ultimately become red blood cells, white blood cells, or platelets. (
  • Leukemia may affect red blood cells, white blood cells, and platelets. (
  • Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. (
  • Platelets that form blood clots to stop bleeding. (
  • Sometimes in AML, too many stem cells become abnormal red blood cells or platelets. (
  • These abnormal white blood cells, red blood cells, or platelets are also called leukemia cells or blasts. (
  • Leukemia cells can build up in the bone marrow and blood so there is less room for healthy white blood cells, red blood cells, and platelets. (
  • Primary human CD4+CD45RO+ T cells were isolated from peripheral blood (PB) mononuclear cells (MNCs) using negative immunomagnetic separation techniques. (
  • To find drugs suitable for repositioning for use against leukemia, samples from patients with chronic lymphocytic, acute myeloid and lymphocytic leukemias as well as peripheral blood mononuclear cells (PBMC) were tested in response to 1266 compounds from the LOPAC 1280 library (Sigma). (
  • In the present study 12 samples of leukemia and 4 samples of normal mononuclear cells were tested in response to 1266 mechanistically annotated compounds including Food and Drug Administration-approved drugs. (
  • Quinacrine was the only compound found with activity in the three leukemia subtypes tested with concurrent low toxicity in normal mononuclear cells, and was, therefore, selected for further preclinical evaluation. (
  • Twelve samples of leukemia (four acute lymphocytic leukemia, four acute myeloid leukemia (AML), four chronic lymphocytic leukemia), as well as peripheral blood mononuclear cells (PBMC) from four healthy donors were used for the compound screen. (
  • The aim of this study was to identify gene expression profiles in peripheral blood mononuclear cells (PBMCs) from sporadic amyotrophic lateral sclerosis (sALS) patients to gain insights into the pathogenesis of ALS. (
  • Neonatal porcine islet transplanted NOD-SCID IL2rγ −/− mice received human peripheral blood mononuclear cells (PBMC) with in vitro expanded autologous Treg in the absence or presence of anti-human interleukin-10 (IL-10) monoclonal antibody. (
  • The other blood components are suspended in plasma, and it allows them to travel through the blood vessels and around your body! (
  • Scientists at Johns Hopkins used a combination of molecular labeling and imaging techniques to create a three-dimensional map of the blood vessels in the mouse skull. (
  • Their approach also reveals niches where stem cell populations lurk, which could help researchers to understand how blood vessels and cells behave in various states of disease or injury. (
  • Understanding the distribution of specific cell types and blood vessels within our body is no easy task, and detailed maps are hard to come by. (
  • We need to see what's happening inside the skull, including the relative locations of blood vessels and cells and how their organization changes during injury and over time," said Warren Grayson, a researcher involved in the study, in a Hopkins press release. (
  • To achieve this, his team has developed a series of tissue processing, staining, and imaging steps that allow them to create impressive 3D maps of the vessels and cells within the skull. (
  • To begin, the team used immunofluorescent stains to label specific cell types and blood vessels with identifying tags. (
  • Leaky blood vessels that lose their ability to protect the spinal cord from toxins may play a role in the development of amyotrophic lateral sclerosis, better known as ALS or Lou Gehrig's disease, according to research published in the April issue of Nature Neuroscience. (
  • Blood vessels run through our brain and spinal cord and supply oxygen and other nutrients, and the lining of those blood vessels constitutes a biochemical barrier to protect the central nervous system from toxins, inflammatory cells, red blood cells, blood products, and a variety of other potential toxic insults. (
  • Rather, the word "barrier" describes an elaborate molecular lattice that lines the insides of the blood vessels that weave throughout the spinal cord. (
  • It's a bit like netting with very small openings that line the inside of blood vessels. (
  • Today, more and more physicians and researchers are discovering the benefits of fluorescence technologies in other areas such as neurosurgery, where it offers the ability to light up blood vessels and tissue. (
  • Depiction of blood flow in the brain under fluorescent light (INFRARED 800 - vessels with blood flow appear brightly lit on the surgical microscope monitor) and under normal lighting (second image). (
  • During surgery, the patient gets injected with a special dye that passes through their bloodstream to the blood vessels at the surgical site. (
  • These cells clog the circulation because they are unable to flow through the small blood vessels of our bodies. (
  • Because the red blood cells are blocked inside the blood vessels, not enough oxygen can be delivered to the other cells and organs. (
  • Glioblastomas are aggressive brain cancers that are nourished by an extensive network of blood vessels. (
  • Because the sickle cells are stiff, they have difficulty traveling through the smallest blood vessels (capillaries), blocking blood flow and reducing oxygen supply to tissues in areas where capillaries are blocked. (
  • Bone marrow is found in the center of most bones and has many blood vessels. (
  • They are stiff and sticky and block small blood vessels when they get stuck together. (
  • Kids who have sickle cell disease may feel pain in different parts of the body when blood vessels get clogged with sickle cells. (
  • Nobody knows exactly when sickle cells might get stuck or which blood vessels might get clogged. (
  • Integrin-α5β1 is not required for mural cell functions during development of blood vessels but is required for lymphatic-blood vessel separation and lymphovenous valve formation. (
  • Unexpectedly, these defects were not caused by loss of α5 from Pdgfrb-Cre expressing mural cells (pericytes and vascular smooth muscle cells), which wrap around the endothelium and stabilise blood vessels, nor by defects in the heart or great vessels, but were due to abnormal development of the lymphatic vasculature. (
  • As a consequence, α5-deficient mice develop dilated, blood-filled lymphatic vessels and lymphatic capillaries that are ectopically covered with smooth muscle cells. (
  • In twin-to-twin transfusion syndrome (TTTS), the communication of placental vessels between the donor and recipient twin creates an imbalance of blood flow resulting in anemia in the donor and polycythemia in the recipient. (
  • The communication of placental vessels between the donor and recipient twin creates an imbalance of blood flow resulting in anemia in the donor and polycythemia in the recipient. (
  • We describe the methods used to quantitate MPs in blood components and discuss the application of these quantitative data in routine transfusion laboratories in order to manage quality, improve the outcomes of transfusions, and minimize their complications. (
  • Many sickle cell patients require frequent blood transfusions, and in most cases, blood from other African Americans will be the perfect match. (
  • It can be extremely difficult to source blood for transfusions of people with very rare blood types. (
  • Likewise, people with blood diseases, such as sickle cell anemia and thalassemia, often require repeated blood transfusions with difficult-to-source blood which has been carefully matched to minor blood group antigens in order to avoid adverse transfusion reactions. (
  • To identify a 'hit list' of proteins for removal, we collaborated with Dr Fiona Regan (NHSBT Hammersmith) who conducted a 15-month NHSBT survey to identify which antigens most commonly caused difficulty in matching blood for transfusions. (
