Immunosuppression News and Research

RSS

Immunosuppression involves an act that reduces the activation or efficacy of the immune system. Some portions of the immune system itself have immuno-suppressive effects on other parts of the immune system, and immunosuppression may occur as an adverse reaction to treatment of other conditions.

Research points to a new approach to treating type 1 diabetes

Scientists at Burnham Institute for Medical Research (Burnham) and the University of California San Diego (UC San Diego) School of Medicine have demonstrated in mice that transplanted pancreatic precursor cells are protected from the immune system when encapsulated in polytetrafluorethylene (PTFE).

Licorice may offer a new approach to preventing colorectal cancer

A chemical component of licorice may offer a new approach to preventing colorectal cancer without the adverse side effects of other preventive therapies, Vanderbilt University Medical Center researchers report.

Gleevec reduces risk of cancer returning in patients with life-threatening gastrointestinal stromal tumors

Data published online and in an upcoming print issue of The Lancet show that Gleevec (imatinib mesylate) tablets, when taken after surgery, substantially reduces the rate of recurrence of Kit-positive gastrointestinal stromal tumors (GIST) compared with placebo.

Liver transplant recipients with hepatitis B may need lifelong antiviral treatment

Patients who undergo liver transplantation for hepatitis B-related liver damage should receive lifelong antiviral treatment to keep the disease from coming back.

Braconid parasite wasps have practiced gene therapy for a hundred million years

Braconid parasite wasps and their caterpillar hosts form a unique host-parasite model: the wasps lay their eggs inside the caterpillars and simultaneously inject some viral particles to get around the host's defenses and control its physiology.

Cell transplantation and diabetes: New sites, new devices

Early attempts at islet cell transplantation to treat diabetes date to the nineteenth century, decades before the discovery of insulin in the 1930s.

May hepatic granulomas be part of the histological spectrum of chronic hepatitis C?

While older large series of patients with hepatic granulomas have found sarcoidosis and tuberculosis to be the most common causes of hepatic granulomas, recent works have noted some patients with chronic hepatic C and hepatic granulomas and no other obvious associations.

Transplanted fat cells restore function after spinal cord injury

A study published in the current issue of Cell Transplantation (Vol.17, No. 8) suggests that mature adipocytes - fat cells - could become a source for cell replacement therapy to treat central nervous system disorders.

Brain deletion of FK506-binding protein enhances repetitive behaviors in mice

A new study reveals a link between dysregulation of a common signaling pathway and repetitive behaviors similar to those associated with multiple neurological and neurodegenerative disorders including, autism spectrum disorders, obsessive compulsive disorder, schizophrenia, and Huntington's disease.

Study compares strategies for BK virus nephropathy

For kidney transplant recipients with a serious complication called BK virus-associated nephropathy (BKVAN), promptly cutting back on anti-rejection drugs reduces the risk of losing the kidney (graft loss), according to a report in the November Clinical Journal of the American Society of Nephrology (CJASN).

Understanding donor-recipient genetics could decrease early kidney transplant complications

Researchers at the University of Pennsylvania School of Medicine have found an association between the genetics of donor-recipient matches in kidney transplants and complications during the first week after transplantation.

First trachea transplant and first tissue transplant without immunosuppression

After 4 years of going from consultation to consultation, Claudia Castillo finally found a solution to her respiratory problems.

Liver transplant recipients face increased risks of developing cancer

A new Canadian study comparing cancer rates of liver transplant patients to those of the general population has found that transplant recipients face increased risks of developing cancer, especially non-Hodgkin's lymphoma and colorectal cancer.

Killing bacteria isn't enough to restore immune function after infection, researchers find

A bacterial molecule that initially signals to animals that they have been invaded must be wiped out by a special enzyme before an infected animal can regain full health, researchers at UT Southwestern Medical Center have found.

Gleevec receives FDA priority review for gastrointestinal stromal tumors after surgery

Novartis has announced that Gleevec (imatinib mesylate) tablets, (known as Glivec (imatinib) outside the US, Canada and Israel), has been granted priority review status by the US Food and Drug Administration (FDA) as the first therapy to be reviewed for use after surgery in kit-positive gastrointestinal stromal tumors (GIST).

Revolutionary technique that could reduce lifelong drugs for transplant patients shows promising findings

Researchers have developed a ground-breaking procedure that could avoid the need for transplant patients to spend the rest of their lives taking a cocktail of drugs to stop their system from rejecting their new organ, according to a series of papers in the August issue of Transplant International.

Discovery of potential key to better drugs to fight Toxoplasmosis parasite

Discoveries by IU School of Medicine scientists have opened a promising door to new drugs for toxoplasmosis and other parasites that now can evade treatments by turning dormant in the body.

Incidence of melanoma and other malignancies among rheumatoid arthritis patients treated with Methotrexate

A chronic, inflammatory disease of unknown origin, rheumatoid arthritis (RA) affects about 1 percent of adults worldwide. Marked by joint destruction, RA often leads to disability and diminished quality of life. It can also lead to an early death from cancer.

Anti-rejection drug sirolimus may prolong organ life in noncompliant kidney transplant patients

New research from the University of California, San Diego Department of Medicine, Division of Nephrology, shows that the anti-rejection drug sirolimus (brand name Rapamune) may help prolong the clinical benefit of transplanted kidneys and delay rejection, especially in patients who do not regularly take their prescribed medications (are "non-compliant"). While the transplant field has been highly successful at reducing rejection and graft loss in the first year, post-transplant, reducing risk for graft rejection in the long-term has proved more difficult.

Biomarkers may reduce the need for biopsies and personalize transplant patient care

Data presented at the 28th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) suggest the potential of a significant impact of using biomarkers to reduce the need for biopsies and personalize transplant patient care.
