New Test Allows Simultaneous Processing of Four STDs

A new test allows simultaneous processing of any combination of four separate sexually transmitted infections: Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Mycoplasma genitalium, from one patient sample. More...

Image: T regulatory cells (also known as Tregs or Regulatory T cells) are essential cells that suppress immune responses of other cells, designed to limit excessive reactions and prevent autoimmunity. Tregs are characterized by the expression of CD4+, CD25+,and Foxp3+, while lacking CD127 (Photo courtesy of BioLegend).

Cellular Mechanism Identified for Severe Viral Hepatitis

It is known that activated immune cells of patients with viral hepatitis destroy hepatocyte, but its regulatory mechanism has not yet been described. Regulatory T cells (Tregs) inhibit activation of other immune cells and thus are important for homeostasis of the immune system. More...
