Study reveals how memory T cells induces immunity in people with Salmonell
Updated : 2 years, 11 months ago IST
Salmonella infections kill about a million people worldwide each year, and better vaccines for both typhoid fever and non-typhoidal Salmonella disease are needed badly. Memory T cells, which are critical for a vaccine that induces a powerful immune response, can be recruited into the liver o

C-reactive protein reduces immune response in inflammatory disease
Updated : 3 years ago IST
C-reactive protein (CRP) biological function has long been unknown. Researchers at Linkoping University in Sweden have discovered that this protein is beneficial in the inflammatory disease systemic lupus erythematosus or SLE. According to the study published in the Journal of Autoimmunity,

Updated : 3 years ago IST
PCB2DG, an anti-inflammatory polyphenol, inhibits glutamine absorption by targeting and directly interacting with the main glutamine transporter protein, alanine serine cysteine transporter 2 (ASCT2). This reduction in intracellular glutamine accumulation in CD4+ T cells also inhibits the pr

Scientists identify protein that's crucial to tumor cells' metabolism
Updated : 3 years ago IST
Tumor cells typically alter their energy metabolism and increase glucose uptake to support their rapid division and spread. This limits glucose availability for immune cells and therefore dampens the body's anti-cancer immune response.
