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.

Blocking an enzyme to overcome immunotherapy resistance in melanoma patients

About 65% of melanoma patients do not respond to immunotherapy. New work by the team of Prof. Max Mazzone (VIB-KU Leuven Center for Cancer Biology) discovered that an enzyme called HPGDS (expressed in a specific subset of macrophages), plays a key role in immunotherapy resistance.

Anti-swelling drug may weaken immune system in brain cancer patients

Swelling caused by brain cancer is a serious problem that can lead to serious side effects and even death. While controlling swelling is important, a new study shows that a commonly prescribed anti-swelling drug suppresses the immune system for weeks after dosage, inhibiting the body's ability to fight the cancer.

EBV exposure linked to life-threatening cancer risk in kidney transplant patients

More than 90% of the adult population in the U.S. is or has been infected with Epstein Barr virus (EBV). EBV is a highly contagious member of the herpes virus family, best known for causing infectious mononucleosis ("mono") and for its association with several cancers and autoimmune diseases.
