Blood proteins, also termed plasma proteins or serum proteins, are proteins present in blood plasma. They serve many different functions, including transport of lipids, hormones, vitamins and minerals in activity and functioning of the immune system. Other blood proteins act as enzymes, complement components, protease inhibitors or kinin precursors. Contrary to popular belief, haemoglobin is not a blood protein, as it is carried within red blood cells, rather than in the blood serum. Serum albumin accounts for 55% of blood proteins, and is a major contributor to maintaining the osmotic pressure of plasma to assist in the transport of lipids and steroid hormones. Globulins make up 38% of blood proteins and transport ions, hormones, and lipids assisting in immune function. Fibrinogen comprises 7% of blood proteins; conversion of fibrinogen to insoluble fibrin is essential for blood clotting. The remainder of the plasma proteins (1%) are regulatory proteins, such as enzymes, proenzymes, and ...
High blood protein (hyperproteinemia) is an increase in the concentration of protein in the bloodstream. High blood protein is not a specific disease or condition in itself, but it might indicate you have a disease.. High blood protein rarely causes signs or symptoms on its own. But sometimes it is uncovered while youre having blood tests done as part of an evaluation for some other problem or symptom.. If your doctor discovers high blood protein during an evaluation, he or she may recommend additional tests to determine if there is an underlying problem.. A total protein test can determine whether you have high blood protein. Other more-specific tests, including serum protein electrophoresis (SPEP), can help determine the exact source, such as liver or bone marrow, as well as the specific protein type involved in your high blood protein levels. Your doctor may order an SPEP if he or she suspects you have a bone marrow disease.. ...

In this article the importance of blood proteins for drug dosing regimes is discussed. A simple mathematical model is presented for estimating recommended drug doses when the concentration of blood proteins is decreased. Practical guidance for drug dosing regimes is discussed and given in the form of a figure. It is demonstrated that correction of drug dosing regimes is needed only for when there is a high level of drug conjugation with blood proteins and a high degree of hypoalbuminaemia. An example of the use of this model is given.

We have tabulated the 77 currently known mutations of the familiar human blood protein, serum albumin (ALB). A total of 65 mutations result in bisalbuminemia. Physiological and structural effects of these mutations are included where observed. Most of the changes are benign. The majority of them were detected upon clinical electrophoretic studies, as a result of a point mutation of a charged amino acid residue. Three were discovered by their strong binding of thyroxine or triiodothyronine. A total of 12 of the tabulated mutations result in analbuminemia, defined as a serum albumin concentration of ,1 g/L. These were generally detected upon finding a low albumin concentration in patients with mild edema, and involve either splicing errors negating translation or premature stop codons producing truncated albumin molecules. A total of nine mutations, five of those with analbuminemia and four resulting in variants modified near the C-terminal end, cause frameshifts. Allotypes from three of the point ...

1. Hemoglobins and serum proteins of herring have been analyzed by agar gel electrophoresis (hemoglobins) and combined starch and agar gel electrophoresis (serum proteins). The material comprises twelve samples from the Norwegian coast and the North Sea and one sample from the east coast of Canada, a total of 1,546 specimens. 2. The results of the hemoglobin analyses were in general agreement with the ontogenetic variation described by WILKINS and ILES (1966). 3. Intraspecific variation was noted in the transferrin components. Three common transferrin types were found and assumed to be controlled by two allelomorphic genes. No relation to age or length was found. Presence of additional weak components complicated the type determination. Hemoglobins in the sera as well as prolonged storage made the type determination unreliable. 4. Observed albumin variations could be explained assuming control by two alleles, while observed variations in other serum protein groups were too weak or too diffuse ...
Proteinuria in normal dogs can be produced at will by parenteral injections of dog plasma.. As the plasma injections are continued the plasma protein concentration rises and at some point protein begins to appear in the urine. The level of plasma protein concentration at which proteinuria appears in normal dogs ranges from 9.6 to 10.4 gm. per cent. This may be termed the renal threshold for proteinuria. Repeat experiments in the same dog show threshold levels to be practically identical.. An interval of days (4 to 26 days) has been noted between the start of plasma protein injections and the appearance of the proteinuria. Larger doses of plasma shorten this interval and the critical plasma protein level is attained sooner.. Considerable amounts of protein may appear in the urine-298 gm. protein during a 52 day period in one instance studied-yet the urine clears in 1 to 4 days after cessation of protein injections. Autopsy shows undamaged kidneys.. Maximal levels of plasma protein concentration ...

The amyloid plaques that form between the brains neurons as it ages are toxic and hence cause the cognitive losses associated with Alzheimers.. "We have, for the first time, demonstrated that the cytotoxic effects of amyloid beta can be prevented by fibrinogen in a dose-dependent manner. Fibrinogen acts as a shield or antidote against its toxicity," lead scientist of the study Debabrata Dash from Banaras Hindu University (BHU), told IANS on Thursday.. Dash said the toxic effects of amyloid beta on blood platelets as well as on neuronal cells can be significantly reduced by pre-treatment with fibrinogen.. "As fibrinogen is already known to bind amyloid beta, it can capture or sequester amyloid beta and prevent the latter from interacting with neuronal cells or platelets," he said.. There is a catch. Fibrinogen does not cross blood-brain barrier (BBB) so this rules out the possibility of the protein gaining entry into brain and capturing the rogue amyloid beta peptides.. "But peptides or small ...

Left: Platelets (shown in the left drawing as grey circles) circulate in blood in a resting state and do not interact with blood proteins. Middle: Adsorption of blood proteins to the biomaterial surface is thought to alter their conformation.. Right: Adsorbed proteins are then thought to activate platelets.. Platelet activation leads to changes in their shape and size, secretion of granules and consequent expression of granule markers (CD62P and CD63), activation of the GPIIb/IIIa integrin complex, exposure of phosphatidyl serine (PS) , which catalyzes thrombin production. Thrombin activates fibrin which polymerizes to form the clot. When activated, platelets also secrete over 200 active substances - growth factors and cytokines - with various, sometimes contradictory functions.[4] Understanding how the secretion of these factors is regulated would allow the regenerative potential of the platelets to be harnessed.. ...
Autoimmunity and macrophage recruitment into the central nervous system (CNS) are critical determinants of neuroinflammatory diseases. However, the mechanisms that drive immunological responses targeted to the CNS remain largely unknown. Here we show that fibrinogen, a central blood coagulation protein deposited in the CNS after blood-brain barrier disruption, induces encephalitogenic adaptive immune responses and peripheral macrophage recruitment into the CNS leading to demyelination. Fibrinogen stimulates a unique transcriptional signature in CD11b(+) antigen-presenting cells inducing the recruitment and local CNS activation of myelin antigen-specific Th1 cells. Fibrinogen depletion reduces Th1 cells in themultiple sclerosis model, experimental autoimmune encephalomyelitis. Major histocompatibility complex (MHC) II-dependent antigen presentation, CXCL10- and CCL2-mediated recruitment of T cells and macrophages, respectively, are required for fibrinogen-induced encephalomyelitis. Inhibition of ...
Human Serum Albumin (HSA) is a protein commonly used in vaccines and often administered for serious burn injuries and liver disease and commonly in short supply due to a lack of donors. That's why researchers from Wuhan University have figured out how to grow it-not in people, but in rice.
By using a chemical procedure in which surfactant molecules, a form of wetting agent, are attached to the protein surface, the researchers remove the water by freeze-drying at low temperature to produce a solid powder. When warmed to room temperature, the powder melts to produce a viscous liquid that contains a very high concentration of myoglobin molecules, while the protein structure remains unchanged even though no water is present.. The experiments, carried out by Professor Stephen Mann, Dr Adam Perriman and Alex Brogan and colleagues in the School of Chemistry at the University of Bristol, and reported in the prestigious journal Nature Chemistry, found that the ability of the liquid protein to reversibly bind oxygen remains unchanged, which means that the potency of the oxygen molecules can be varied in response to the pressure applied.. The resulting liquid is a simplified form of "artificial blood" that might be used as a smart solvent-less fluid of highly concentrated protein for oxygen ...
In NIH-supported study, blood test in symptom-free volunteers links levels of specific protein with beta amyloid deposits. Scientists are seeking ways to detect the earliest stages of Alzheimers disease, since harmful changes may be taking place in the brain years before symptoms appear. Now, researchers report that a blood test detecting a specific protein in blood samples from cognitively normal older people may reflect the levels of beta-amyloid protein in the brain - a hallmark of the disease. Supported in part by the National Institutes of Health, the findings may eventually lead to a blood test that helps predict risk for Alzheimers disease and who may be a good candidate for participating in clinical trials ...
Years before symptoms of Alzheimers disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tuebingen now show that a protein found in the blood can be used to precisely monitor disease progression long before first clinical signs appear. This blood marker offers new possibilities for testing therapies. The study was carried out in cooperation with an international research team and published in the journal Nature Medicine.. The fact that there is still no effective treatment for Alzheimers is partly because current therapies start much too late, says Mathias Jucker, a senior researcher at the DZNEs Tuebingen site and at the HIH. He headed the current study. In order to develop better treatments, scientists therefore need reliable methods to monitor and predict the course of the disease before symptoms such as memory ...

The effects of systemic sclerosis can range from only minimal skin changes to a rapidly progressive course that involves multiple organs and causes early death. It clearly is of great value to physicians to have reliable predictors for patients who may have a poor prognosis. This major multicenter study is prospective, has a wide geographic representation, uses uniform classification and diagnostic criteria, and has a long-term follow-up. Appropriate statistical methods used are used. A total of 484 information items were obtained on each patient, and the paper details 72 selected variables subdivided into 9 appropriate subsets. The data clearly show that the patients with the worst survival were those over 64 years of age with renal disease and younger patients with anemia. Other predictors included severe pulmonary disease and reduced total serum protein levels. These observations alert the physician to target studies at the function of the kidney, lung, heart, and hemopoietic systems. It ...

Blood clot crystals. Coloured scanning electron micrograph (SEM) of crystals of albumin from a blood clot. Albumin is the most abundant protein in the blood plasma. When the skin is cut, small blood vessels are ruptured, releasing blood. Some proteins in the blood plasma (such as albumin) harden in the air to form crystals (pink) over the wound. Other blood proteins then help form a clot over the wound, preventing excessive blood loss, and keeping the wound free of bacteria and other foreign bodies. Albumins other roles in the blood include helping to maintain the levels of hormones and calcium, and assisting water flow between the bloodstream and body tissues. - Stock Image P260/0105
