Abstract

The small intestine is a well documented target organ in mouse and human GVHD, and diarrhea is a prominent part of the clinical GVHD syndrome. Although a plethora of systemic immune deficits has been documented in GVHD, the integrity of the small intestinal immune system has not been investigated. A correlation has not been demonstrated between systemic immune dysfuction and the incidence of lymphomas in mouse GVHD survivors. If gastrointestinal immune deficiency exists in mouse GVHD, its possible relationship to GVHD lymphomas, frequently abdominal. should be investigated. GVHD was produced in newborn BLA (C57 BL/Ka females x BALB-C males) mice house in a specific pathogen-free environment by the i.p. inoculation of 10(7) male BALB-C spleen cells. Control mice received syngeneic spleen cells. Twenty GVHD and 16 control mice were sacrificed at 3 weeks and specimens of duodenum were removed for routine histologic and immunofluorescent examination. All but one GVHD mouse (95%) had virtually absent duodenal IgA and IgM. Duodenal cellular fluorescence was demonstrated in all controls. A significant duodenal immunoglobulin deficit has been demonstrated in 3-week-old GVHD mice. The relationship of this finding to GVHD diarrhea, wasti...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
