Activated T-Cells Could Help In The Battle Against HIV

...that binds to certain immune cells, and interferon gamma were added to dendritic cells. In the study, white blood cells called monocytes were obtained from both HIV patients and individuals not infected with the virus. In the laboratory, the researchers coaxed them to differentiate into mature dendritic ...

Deficient 'Scout Cells' Causes Cancer in Transplant Patients

...Fb and a second immune substance called interferon gamma (IFNg) might influence development of the cancer. The study showed that some people have a normal genetic difference that causes them to have lower levels of IFNg in the body and others to have higher levels. The researchers then injected white blo...

Protective Intestinal Antibiotic Protein Discovered

...with a sweet tooth." The protein, called RegIII gamma in mice and HIP/PAP in humans, belongs to a protein class called lectins, which bind to sugar molecules. These particular lectins' seek-and-destroy mission may help to create an "electric fence" that shields the intestinal surface from invading bacte...

Cancer Drug Helps An Anti-Cancer Virus To Act More Exhaustively

... stop making an immune substance called interferon gamma (IFNg). One key effect of IFNg is to attract immune cells to an infection site. The production of the substance could therefore intensify the immune response against the anti-cancer virus. Furthermore the researchers found that in rat brain tumours...

White Blood Cells Can Both Hurt and Help Transplanted Kidneys

...r necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma), which are known to produce cellular damage in kidneys. These chemicals are produced by T cells. The mice that underwent fake surgery also had an elevated level of T cells when compared to the normal mice, but these cells did not releas...

Study Reveals Effects of WBCs on Transplanted Kidney

...r necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma), which are known to produce cellular damage in kidneys. These chemicals are produced by T cells.The mice that underwent fake surgery also had an elevated level of T cells when compared to the normal mice, but these cells did not release T...

Antioxidant-Rich Pecans Protect Against Unhealthy Oxidation in the Body

...ans are especially rich in one form of vitamin E – gamma tocopherol. 'We found that eating pecans increased levels of gamma tocopherol concentrations in the blood and subsequently reduced a marker of lipid oxidation,' adds D...

A New Option For AIDS Treatment - Radioimmunotherapy

...cells, and deliver the radiation slowly. Alpha or gamma particles are emitted , and either the cell membrane is ruptured or the essential DNA is damaged during this procedure. It was found that the number of HIV infected cells fell in the treated mice compared to the other mice , which had been given an...

Sticky Proteins Provide New Insight Into Drug Action

...ivated, the alpha protein splits from the beta and gamma subunits, which are irrevocably stuck together as a beta-gamma pair. Each half of the now dissociated G protein can cause the cell to do something different. “Sometimes they help each other out; sometimes they work at cross purposes,” says Dr. Lamber...

Study Explains How NSAIDs Halt Cancer Growth

Oral Flu Vaccine On The Horizon In Russia

...he vaccine, called Korauban, is an immunostimulant gamma interferon inductor that is closely related to ordinary cellulose. The initial clinical candidate form will include antigens from three inactivated viruses (A1, A2, B). An undisclosed component, permitting 12-month tablet stability, will be used to d...

Erroneous Laboratory Operation May Lead To a Cancer Drug

...breaks it down. This indirectly indicates that the gamma compound could actually counter the effect of tumor cells to chemotherapy. Schaefer also intends to pursue this study further and conduct more trials with mice on the same subject. JYT...

Genes for Nicotine Dependence Identified

... The researchers also identified genes related to gamma aminobutyric acid (GABA) receptors, another set of proteins vital to nerve cell function. Both GABA and nicotinic receptors had been suspected of involvement in nicotine addiction, but these findings strengthen those suspicions. The studies also id...
