Graft vs Host Reaction
Graft vs Host Disease
White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.
Graft vs Tumor Effect
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

Hematopoietic Stem Cell Transplantation
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
Bone Marrow Transplantation
Lymph Node Excision
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.
Hepatitis, Infectious Canine
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

Blood Group Incompatibility
An antigenic mismatch between donor and recipient blood. Antibodies present in the recipient's serum may be directed against antigens in the donor product. Such a mismatch may result in a transfusion reaction in which, for example, donor blood is hemolyzed. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984).

Adoptive immunotherapy of a Gross virus producing lymphoma and a methylcholanthrene-induced fibrosarcoma in tolerant rats. (1/429)Immunological tolerance to Gross virus-specific transplantation antigens in rats given neonatae transfer of donor lymphoid cells beneath the kidney capsule of syngeneic recipient rats. Immune or normal donor cells invariably developed a cell-mediated immune reaction in kidneys of GV-tolerant recipients, presumably against GV antigens present on the surface of recipient lymphoid cells in the kidney. Spleen and lymph node cells from tolerant rats failed to develop a reaction in tolerant recipients, but developed a strong reaction to histoincompatible antigens in the kidneys of semisyngeneic tolerant rats. The immunologically tolerant state in the rats could be broken by adoptive transfer of spleen and lymph node cells from syngeneic rats immunized with GV-induced lymphoma cells. Immunotherapy of a GV-induced and also a GV-infected methylcholanthrene-induced fibrosarcoma growing in tolerant rats was successful when immune spleen and lymph node cells were administered i.p. 3 days after s.c. inoculation of 2 X 10(7) tumor cells in the case of the lymphoma, and 1 day after inoculation of 5 X 10(6) tumor cells in the case of the fibrosarcoma.

Nitric oxide mediation of active immunosuppression associated with graft-versus-host reaction. (2/429)In the immunosuppression accompanying the lethal systemic graft-versus-host reaction (GVHR) directed against minor histocompatibility antigens in irradiated adult mice, we previously determined that non-T, non-B, L-leucine methyl ester (LME)-sensitive cells were implicated via two different mechanisms: one, which is interferon-gamma (IFN-gamma)-dependent and affects both T-cell proliferative responses and thymus-independent antibody production by CD5(+) B cells; and a second, which is IFN-gamma-independent and affects B-cell proliferative responses. Because IFN-gamma induces the production of nitric oxide (NO), a potent immunosuppressive molecule, we investigated the involvement of NO in the suppression mediated by the LME-sensitive cells. Inducible NO synthase (iNOS) mRNA, iNOS protein, and the stable end products of iNOS pathway, L-citrulline and nitrite, were detected early in GVHR in LME-sensitive spleen cells taken ex vivo and could be amplified in vitro by T and B mitogens. Inhibition of NO production with arginine analogs (aminoguanidine, N(G)-monomethyl-L-arginine [LMMA]), like anti-IFN-gamma antibodies, reversed suppression of both T-cell responses to concanavalin A and CD5(+) B-cell responses, but not of B-cell response to lipopolysaccharides (LPS). The GVHR-associated, IFN-gamma-dependent immunosuppression of T-cell proliferation and of antibody synthesis by CD5(+) B cells is the consequence of NO production by LME-sensitive cells. Immunohistochemical analyses indicate that these cells belong to the macrophage lineage. (+info)
Differential roles of IL-1 and TNF-alpha on graft-versus-host disease and graft versus leukemia. (3/429)We demonstrate an increase in graft-versus-host disease (GVHD) after experimental bone marrow transplant (BMT) when cyclophosphamide (Cy) is added to an otherwise well-tolerated dose (900 cGy) of total body irradiation (TBI). Donor T cell expansion on day +13 was increased after conditioning with Cy/TBI compared with Cy or TBI alone, although cytotoxic T lymphocyte (CTL) function was not altered. Histological analysis of the gastrointestinal tract demonstrated synergistic damage by Cy/TBI and allogeneic donor cells, which permitted increased translocation of LPS into the systemic circulation. TNF-alpha and IL-1 production in response to LPS was increased in BMT recipients after Cy/TBI conditioning. Neutralization of IL-1 significantly reduced serum LPS levels and GVHD mortality, but it did not affect donor CTL activity. By contrast, neutralization of TNF-alpha did not prevent GVHD mortality but did impair CTL activity after BMT. When P815 leukemia cells were added to the bone marrow inoculum, allogeneic BMT recipients given the TNF-alpha inhibitor relapsed at a significantly faster rate than those given the IL-1 inhibitor. To confirm that the role of TNF-alpha in graft versus leukemia (GVL) was due to effects on donor T cells, cohorts of animals were transplanted with T cells from either wild-type mice or p55 TNF-alpha receptor-deficient mice. Recipients of TNF-alpha p55 receptor-deficient T cells demonstrated a significant impairment in donor CTL activity after BMT and an increased rate of leukemic relapse compared with recipients of wild-type T cells. These data highlight the importance of conditioning in GVHD pathophysiology, and demonstrate that TNF-alpha is critical to GVL mediated by donor T cells, whereas IL-1 is not. (+info)
Vaginal outflow tract obstruction by graft-versus-host reaction. (4/429)We describe a 25-year-old patient suffering from vaginal outflow obstruction which presented as secondary amenorrhea during hormone replacement therapy. The patient had undergone bone marrow transplantation for acute myelocytic leukemia, which caused ovarian failure. Oral mucositis associated with a chronic GVH reaction also occurred. For 3 years she was treated with HRT and had regular menses which gradually ceased and were associated with dyspareunia and abdominal cramps. Abdominal US examination demonstrated hematocolpus. Sonography guided adhesiolysis of a dense vaginal obstruction allowed free drainage with histologic confirmation of a graft-versus-host reaction. The possibility of vaginal stricture or obstruction should be considered in all patients after BMT who suffer from graft-versus-host disease. (+info)
Visualization, fate, and pathogenicity of antigen-specific CD8+ T cells in the graft-versus-host reaction. (5/429)To follow the fate of alloreactive T cell effectors in graft-vs-host disease, Ld-specific CD8+ T cells from C57BL/6 2C TCR-transgenic donors were transplanted into sublethally irradiated (750 cGy) Ld+ or Ld- recipients. In Ld- C57BL/6 or (BALB/c-dm2 x C57BL/6)F1 recipients, naive 2C T cells engrafted and survived long term, but did not acquire effector function. In Ld+ (BALB/c x C57BL/6)F1 recipients, 2C T cells engrafted, expanded, became cytolytic, destroyed host B cells and double-positive thymocytes, and later disappeared. Despite marked damage to lymphoid and hemopoietic cells by 2C T cells, no significant pathology was detected in other organs, and recipients survived. Ld+ (BALB/c x C57BL/6)F1 recipients died when LPS/endotoxin was administered on day 7 after cell transfer, while Ld- (BALB/c-dm2 x C57BL/6)F1 recipients survived. Our findings show that under certain conditions, a CD8+ T cell population recognizing an extremely limited repertoire of Ags can initiate graft-vs-host disease. (+info)
Photochemical treatment with S-59 psoralen and ultraviolet A light to control the fate of naive or primed T lymphocytes in vivo after allogeneic bone marrow transplantation. (6/429)Donor leukocyte infusions after allogeneic bone marrow transplantation can provide a curative graft-vs-leukemia (GVL) effect, but there is a significant risk of graft-vs-host (GVH) disease. A simple and effective method for controlling the fate of naive or primed T-lymphocytes in vivo without eliminating their beneficial properties is needed. In this report, photochemical treatment (PCT) ex vivo with a synthetic psoralen (S-59) and UVA light was evaluated as a pharmacological approach to limiting the proliferation and GVH potential of naive and primed donor T cells in vivo. S-59 rapidly intercalates into and cross-links DNA on UVA illumination. The effects of PCT on T cells were found to be both S-59 and UVA dose dependent. With selected PCT regimens, treated T cells still expressed activation markers (CD25 and CD69) and secreted IL-2 on activation, but they showed limited proliferative capacity in vitro and in vivo. Clonal expansion of CTL in MLR was reduced after PCT, but short term lytic activity of primed CTL was not affected. In a murine model of MHC-mismatched bone marrow transplantation, the addition of PCT-treated T cells to T-depleted bone marrow facilitated donor engraftment and complete chimerism without causing acute or chronic graft-vs-host disease. Allospecific GVL reactivity was reduced but not eliminated after PCT treatment. In an MHC-matched model using host-presensitized donor T cells, PCT significantly reduced GVH-associated mortality without eliminating GVL reactivity. Thus, PCT ex vivo offers a simple, rapid, and inexpensive method by which to control the fate of naive and primed T cells in vivo. (+info)
Induction of autoimmunity in a transgenic model of B cell receptor peripheral tolerance: changes in coreceptors and B cell receptor-induced tyrosine-phosphoproteins. (7/429)Abrogation of peripheral tolerance in transgenic mice that express a uniform B-cell receptor may create a powerful tool to examine the molecular mechanisms that underlie the autoimmune response in B cells. Here we report that processes that induce a systemic lupus erythematosus-like syndrome in normal mice, namely chronic graft vs host reaction, trigger systemic autoimmunity in a well-established transgenic mice model of B cell receptor peripheral tolerance. The induction of graft vs host reaction in mice that carry both a rearranged B cell Ag receptors specific for hen egg lysozyme and expressing chronically circulating hen egg lysozyme Ag resulted in induction of high and sustained levels of circulating anti-hen egg lysozyme autoantibodies and glomerulonephritis with proteinuria. This was associated with marked changes in expression of cell-surface proteins, such as CD23 and complement receptor 2. B cells from the graft vs host-induced mice could proliferate in vitro in response to self-Ag, and upon stimulation with anti-IgD demonstrated rapid phosphotyrosine phosphorylation of specific proteins, which could not be induced in the anergic double transgenic B cells. Conversely, loss of tolerance was not associated with a higher induction in the level of Syk kinase phosphorylation following stimulation with anti-IgD. Taken collectively, these data establish that 1) processes that induce a systemic lupus erythematosus-like syndrome in normal mice can abrogate peripheral tolerance in transgenic mice expressing self-tolerized B cells, and that 2) loss of tolerance in this model is associated with marked changes in surface expression of B cell coreceptors as well as with selective changes in IgD-induced signaling by discrete tyrosine-phosphoproteins, but not Syk kinase.

Effects of graft-versus-host reaction on intrahepatic islet transplants. (8/429)The use of donor-specific bone marrow transplantation might represent a valuable approach for the induction of hyporesponsiveness to concurrent allogeneic organ and tissue grafts. In this setting, the occurrence of subclinical forms of graft-versus-host reaction (GVHR) can seldom be formally ruled out. When systemic administration of donor-specific bone marrow is performed together with intraportal transplantation of islets of Langerhans, GVHR might damage the implanted islets through an innocent bystander mechanism. The liver is, in fact, a prominent target of GVHR, and islets are sensitive to the noxious effects of proinflammatory mediators, including selected cytokines produced during GVHR. A parent (Lewis) to F1 (Lewis x Brown Norway) splenocyte transfer model was used to induce GVHR in rats. Islets were also obtained from Lewis donors and implanted into F1 recipients to examine the effects of GVHR on islet function in the absence of rejection. Selected doses of splenocytes were infused in F1 recipients to induce GVHR. When 150 x 10(6) cells were administered, all recipients developed clinical lethal GVHR. When 100 x 10(6) or 80 x 10(6) cells were given, lethal GVHR was observed in 40 and 20% of the F1 animals, respectively. A transient clinical syndrome occurred in the remaining animals and spontaneously subsided; histological findings consistent with persistent low-grade GVHR were observed in these animals at the time of death several months after splenocyte inoculation. When simultaneous splenocyte infusions and islet grafts were performed in chemically diabetic animals, no adverse effect of either clinical or subclinical GVHR was observed on islet function. Blood glucose profiles were normal, as were intravenous glucose tolerance test profiles. In conclusion, GVHR does not seem to adversely influence function of islets of Langerhans implanted intrahepatically in this parent to F1 experimental model. (+info)
Most recent papers with the keyword Amphiregulin | Read by QxMD
Allogeneic immune cells, particularly T cells in donor grafts, recognize and eliminate leukemic cells via graft-versus-leukemia (GVL) reactivity, and transfer of these cells is often used for high-risk hematological malignancies, including acute myeloid leukemia. Unfortunately, these cells also attack host normal tissues through the often fatal graft-versus-host disease (GVHD). Full separation of GVL activity from GVHD has yet to be achieved. Here, we show that, in mice and humans, a population of interleukin-9 (IL-9)-producing T cells activated via the ST2-IL-33 pathway (T9IL-33 cells) increases GVL while decreasing GVHD through two opposing mechanisms: protection from fatal immunity by amphiregulin expression and augmentation of antileukemic activity compared with T9, T1, and unmanipulated T cells through CD8α expression ...
The Divergence of Lymphocyte Development Pathways | The Journal of Immunology
In retrospect, it seems obvious that effective immunity requires the coordinated activities of many cell types. Given their functional specialization and differences in lifespans, it makes sense that different kinds of lymphocytes are initially generated and then replenished in separate sites. There were tantalizing clues to this in the early 1960s, but a remarkable convergence of clinical findings and studies with experimental animals was needed to delineate clearly the origins of what now are known as B and T cells. Using a chicken model, Max Cooper first showed that the cells that derived from the bursa of Fabricius were responsible for Ab production, whereas the thymus-derived cells were the effectors of delayed-type hypersensitivity and graft vs host reactions (1, 2).. Modifying methods developed by Glick, Warner, and others (3, 4), Cooper combined surgical thymectomy and/or bursectomy of posthatched chickens with sublethal irradiation. This novel strategy effectively eliminated lymphocytes ...

Supplementary Materialsimmunology. Rotation desk extracted from PCA. Sources ( em 92 /em C em 100 /em ) Abstract Although critical illness has been associated with SARS-CoV-2-induced hyperinflammation, the immune correlates of severe COVID-19 remain unclear. Here, we comprehensively analyzed peripheral blood immune perturbations in 42 SARS-CoV-2 infected and recovered individuals. We determined intensive activation and induction of multiple immune system lineages, including T cell activation, oligoclonal plasmablast enlargement, and trafficking and Fc receptor modulation on innate lymphocytes and granulocytes, that recognized serious COVID-19 cases from healthy donors or moderate or SARS-CoV-2-recovered severity individuals. We found out the neutrophil to lymphocyte percentage to be always a prognostic biomarker of disease body organ and severity failing. Our results demonstrate wide innate and adaptive leukocyte perturbations that differentiate dysregulated SC 66 host reactions in serious ...

Dr McGee is referring Tyler back to SCCA for testing and possible treatment. Most likely, Tyler would get a Donor Lymphomcyte Infusion. This is like a booster shot of white blood cells from his father, that should stimulate the marrow to attack the leukemia cells that are floating around in there. The goal of this treatment is to get Tyler back into full remission, but would likely cause a recurrence and possibly an increase in Tylers Graft vs Host (GVHD) symptoms, but would also increase the Graft vs. Leukemia effect (beneficial). I know this all sounds very complicated, but we are working through this and finding out about the procedure ...

Separate effects of irradiation and of graft-versus-host reaction on rat mucosal mast cells. | Gut
T cell mediated immune responses in the gut can produce enteropathy and malabsorption. We have investigated the relevance of mucosal mast cells (MMC) to the mechanisms of this enteropathy by using graft-versus-host reaction (GvHR) in the rat as a model of mucosal delayed type hypersensitivity. Measurements of mucosal architecture, intraepithelial lymphocytes (IEL) and MMC counts were performed in control and experimental rats, and release of rat mast cell protease II (RMCPII) into the bloodstream was used as an index of MMC activation. In unirradiated rats, jejunal MMC count was increased on day 14 of the GvHR (mean 272/mm2 v 182 in controls, p less than 0.01), as was serum RMCPII (p less than 0.01). Irradiated rats (4.5 Gy, reconstituted with isogeneic spleen cells) had low counts of IEL and crypt hyperplasia seven to 14 days after irradiation. Irradiated rats with GvHR (induced by ip injection of parental strain spleen cells) and studied on days 7, 10 and 14, had significant enteropathy with ...
Efficacy of Total Lymphoid Irradiation in Intractable Rheumatoid ArthritisA Double-Blind, Randomized Trial | Annals of Internal...
Twenty-six patients participated in a randomized, double-blind study of the efficacy of total lymphoid irradiation in the treatment of intractable rheumatoid arthritis. All 26 patients, for whom therapy with gold compounds and penicillamine had failed, would ordinarily have been considered candidates for cytotoxic or antimetabolite drug therapy. Thirteen patients randomly assigned to receive full-dose total lymphoid irradiation (2000 rad) and 11 patients assigned to receive control low-dose total lymphoid irradiation (200 rad) completed radiotherapy. Alleviation of joint disease activity was significantly greater in the high-dose group as judged by morning stiffness, joint tenderness, and functional assessment (global composite score) at 3 and 6 months after radiotherapy. The high-dose group had a marked reduction in both T-lymphocyte function and numbers, but this finding was not observed in the low-dose group. Complications seen in the high-dose but not low-dose group included transient ...

One of the most important complications associated with bone marrow transplantation (BMT) is graft-versus-host reaction (GVHR) altering different organs. The immunosuppressive regimen frequently abates the severity of cutaneous lesions to a peculiar lymphocyto-depleted GVHR (LD-GVHR) with scant recognizable inflammatory cells and almost absence of epidermal injury. The recently revisited histological criteria for cutaneous GVHR are of little help in diagnosing such LD-GVHR. As calprotectin (L1-protein) has been reported to be expressed in several types of stressed epithelia, we assessed the epidermal calprotectin expression during LD-GVHR. Calprotectin expression was studied by immuno-histochemistry using the Mac 287 moAb in 50 ...

If I understand, the trade-offs at play here are effectiveness against the cancer versus the risk of Graft vs. Host Disease. The greater number of my cells given to her, the greater effect against the cancer but also the higher the risk of GvHD.

The T-cell-mediated cytotoxic potential of spleen cells from the injected F1 mice was assessed from 4 to 21 d later by in vitro sensitization with trinitrophenyl-modified parental or syngeneic F1 spleen cells (TNP-self) or with allogeneic spleen cells. The cytotoxic potential of the F1 mice to TNP-self as well as to alloantigens was abolished or severely depressed throughout this period when the respective H-2k,a,d parental spleen cells were injected. In contrast, the cytotoxic potential was unaffected or only marginally reduced when H-2b parental cells were injected. The induction of depressed cytotoxic activity was shown to be a result of a population of parental radiosensitive T lymphocytes. The results should be discussed with respect to (a) the genetic and mechanistic parameters associated with the differential ...
Health Article - The War of Cells: Graft vs. Host Disease - AARP
If you are a bone marrow transplant recipient with symptoms of GvHD, talk to your doctor as soon as possible. During your visit, tell your doctor about all of your symptoms, no matter how minor they may seem. If your doctor suspects you have GvHD, you will receive a blood test. This test will look for high levels of white blood cells, which usually indicate an infection.. If your test shows a high white blood cell count, you may need a tissue biopsy. The biopsy is usually performed while you are under sedation. It can also be performed with just a local anesthetic. A small piece of tissue will be removed from the area affected by GvHD. It will then be sent to the lab and tested for abnormalities. In many cases, a urinalysis (urine test) will also be used to detect signs of infection. Urine tests can be used to rule out conditions such as diabetes or bladder infections.. ...
B cell survival holds key to chronic graft vs. host disease | EurekAlert! Science News
B cells, which produce proteins called antibodies, are one type of immune cell involved in GVHD. In a paper published in the journal, Blood, a team from the University of North Carolinas Lineberger Comprehensive Cancer Center, shows in the laboratory that B cells from patients with chronic GVHD are much more active than cells from patients without the disease. The team also outlines the cell signaling pathways that contribute to this increased activity -- identifying a promising target for developing new therapies for the diseases.

The next proposed course of action is a round or so of rituximab (the drug that worries me so much), along with total lymphoid irradiation and possibly cytoxan administered intravenously.

For the first time in some time, we are again hearing murmurs that some form of external assist device might become necessary at some point. Sorry for all the medical-speak -- its virtually impossible to explain these things any more easily. Suffice it to say that Patty has worked her way, without real success, through most of the traditional solutions to the antibodies issue, and is now trying lesser-tested approaches in the hope something tips the scales in her favor ...

Plant Disease 1989 | Experimental Hosts of the Beet Leafhopper-Transmitted Virescence Agent
The vector Circulifer tenellus was used to inoculate 60 species of plants with the beet leafhopper-transmitted virescence agent (BLTVA). A wide range of host reactions was seen in 43 species, including floral gigantism, host induction response, internode elongation, internode shortening, leaf deformation, leaf mottling, proliferation, stunting, tip necrosis, virescence, wilting, and yellowing. No nonsymptomatic hosts were found, but 17 plant species did not develop symptoms of infection after exposure to inoculative leafhoppers; this included all the monocots tested. A number of plants that have been reported as hosts of economically important MLO diseases also proved to be hosts of BLTVA. In seven host species, flowering was induced in plants grown under environmental conditions that would normally be noninductive for flowering.. ...

Bledsoe Battle: July 2009
His right eye was even more red than normal and seemed to be oozing a little bit on Saturday. On Sunday and Monday, his eyes actually crusted shut as he slept overnight and continued to ooze all day long. We were worried because he has had eye sensitivity from the lack of tears (which is most likely mild Graft vs Host Disease) and this new symptom seemed to coincide with a new reduction in his tacrolimus (the immunosuppressant drug). Hes been reducing one of his two daily doses every couple of weeks or so. He is on .5 mg in the morning and evening this week, then .5 mg in the morning and 0 in the evening next week, and then he is DONE!!! This means we are rapidly approaching our important 6 month mark ...
Stem cell transplants | Cancer Survivors Network
Hi, I am a 41 year old female who was Dx with MM when I was 38. I was at stage three with 50% cancer cells. I tried the Autologus transplant first which is where they use my own stem cells. It took four months of chemo before the actual transplant and then three months isolation after the one month stay in the hospital. I was feeling good for about 7 months and then relapsed. In March of this year, 2003, I had the Allogenic transplant using my sisters stem cells. Although I have not completed the first 100 days yet, I can already tell Im doing much better. I will have follow up tests the end of June to see how well this worked. Of course the big fear was the GVH disease, but I have been good, taken my meds, eat the right things and have been very blessed that I have not had any signs of it. I met a girl at clinic who did end up with it and although she looked thin, she seemed to be doing great. What city do you have to move to in order to get your transplant? I was lucky, the U of M is right in ...

BONE MARROW ORIGIN OF IMMUNOLOGICALLY COMPETENT LYMPHOCYTES IN THE RAT | JEM
Rat bone marrow is deficient in immunologically competent cells when compared with the peripheral pool of circulating small lymphocytes. However, circulating lymphocytes capable of initiating a lethal graft vs. host reaction can develop from myeloid precursors. In adult rats inoculated at birth with parental strain bone marrow cells, the thoracic duct lymph contains cells having the immunological capability of the marrow donor. The evidence suggests that immunologically competent lymphocytes derive from cells normally resident in bone marrow and probably not from precursors in the peripheral lymphocyte pool.. ...
Cryptococcoma of the ilium in an immuno-competent child - a case report and review of the literature
Discussion. Infections occur through inhalation of yeast-like organisms which enter smaller respiratory passages and then remain dormant depending on the host reaction.6 The pigeon appears to be the chief vector for the distribution and maintenance of Cryptococcus neoformans. The organism is usually found in debris in pigeon roosts or other bird nests.7 Direct inoculation through the skin may also occur.5 There are two types of Cryptococcus neoformans infections, but the manifestation depends on the host response rather than the strain of the organism,8 with infection rarely occurring in immuno-competent hosts.9 The first type occurs in immuno-compromised individuals where the infection spreads rapidly to involve most organ systems, especially the central nervous system (CNS). The second occurs in immuno-competent individuals where the bodys natural defence mechanism prevents systemic disease. In these cases organisms can be disseminated haematogenously to distal sites, where re-activation can ...

Procedure Description. During this treatment we will collect 30-60mls of your own blood. Then we will spin your blood in a centrifuge, which separates out plasma and platelets via a special filter. The PRP portion of your blood is then injected backed into your skin mixed with ACell to stimulate new collagen, hair cell growth, and cell rejuvenation. The product injected is 100% a by-product of your own blood (autologous).. ACell produces extracellular matrix (ECM), the by-product of porcine urinary bladder tissue that has proven regenerative properties. The product is stripped of all cells, as well as muscle tissue, to prevent graft-versus-host reactions (allergic reactions) when introduced in humans.. ACells ECM also provides growth factors and proteins necessary for tissue regeneration and sets up a temporary non-cross-linked scaffolding for the tissue reconstruction that mimics the surrounding healthy-but-damaged tissue. This scaffolding contains and slowly releases growth factors (VEGF ...

TY - JOUR. T1 - Antibody synthesis by transferred lymphoid cells. T2 - The influence of the host genetic environment on the duration of the immune response. AU - Wakefield, June D.. AU - Rose, Noel R.. PY - 1968. Y1 - 1968. N2 - Spleen cells from 129/JaxHe and C3H/He mice, actively immunized with bovine serum albumin, were transferred to 129/ JaxHe, C3H/He, and F1 hybrids of these strains. Grafts of spleen cells from the two strains showed similar patterns of behavior, in that the antibody to bovine serum albumin was detectable for at least 60 days in syngenie recipients when male spleen cells were transferred to male recipients. Females accepted male cells transiently; antibody rarely was present at the 4th week. Parental spleen cells produced antibody for limited periods of 1 month in F1 mice. The two mouse strains differed in their responsiveness to certain grafts of skin. Female 129 mice rejected male 129 skin grafts, whereas C3H females appeared to accept grafts of C3H male skin. Such ...
A case for the graft-versus-host disease as a model for B cell-mediated autoimmunity.
Following allogenic hematopoietic stem cell transplantation (HSCT), patients with autoimmune disease or hematopoietic malignancy may develop acute or chronic graft-versus-host (GvH) disease. B lymphocytes, from the recipient as well as from the donor, have recently been implicated in the pathogenesis of such disturbances. Their deleterious effects are accounted for by other tasks B lymphocytes accomplish than the antibody production. We highlight herein some recent observations in the context of B cells in the GvH disease.
So youve been diagnosed with Ocular Graft vs. Host Disease (GVHD) …
GVHD may cause severe eye dryness that results in permanent vision loss without treatment.. Hematologic stem cell transplantation is commonly used to repair the immune system following high intensity radiation treatment. Simply put, a donor gives healthy blood to somebody with a weakened immune system to jump start their immunity and prevent them from becoming sick.. It is common for the new blood cells (the graft) to view the recipient (the host) tissue as foreign. This results in tissue damage, often targeting the tear glands of the eyes. This is termed Ocular Graft versus Host Disease (GVHD). Damaged tear glands tend to stop working well, if at all, and result in a severely dry eye surface. This dryness is painful, debilitating, and may cause permanent vision loss if not treated quickly.. The solution? Scleral contact lenses. These lenses restore the ability to live a day without worrying whether or not your eye irritation will keep you in bed all day.. Schedule a Scleral contact lens ...
Natural enzyme provides potential new approach for treating graft-vs-host-disease - Healthcanal.com : Healthcanal.com
ANN ARBOR, Mich. - A natural enzyme derived from human blood plasma showed potential in significantly reducing the effects of graft-vs.-host disease, a common and deadly side effect of lifesaving bone marrow transplants.. Researchers from the University of Michigan Comprehensive Cancer Center looked at the drug alpha-1-antitrypsin, which is approved by the U.S. Food and Drug Administration for use in people who have a genetic mutation that makes them deficient in a certain enzyme. This drug has been used in many of these patients over extended periods of time and is known to cause minimal side effects.. More important, there are no known reports of increased susceptibility to infections. This is key for people with graft-vs.-host disease, where existing treatment options tend to suppress the immune system, putting patients at risk of infection. Graft-vs.-host disease is a major complication of bone marrow transplants using marrow from a donor, called an allogeneic transplant. This often-deadly ...

The docs were concerned that he might be experiencing a little of the Graft vs. Host disease in his gut based on his poop output and some tummy & chest pain. Nothing major and nothing too serious and in fact its quite common post transplant. Its treated with steroids and most likely just goes away. The doctor that performed the procedure turned over some really wonderful photos of Hunters insides..........a few sides of him that I have never seen before. Didnt think there were any left??? So now we have just a few more wonderful pics for Hunters baby book. Ill put those right next to his little foot prints and his little ringlet of hair...............that has now fallen out twice.
