Scientists have detected previously unnoticed chemical signals that individual cells in the immune system use to communicate with each other over short distances. The signals the researchers detected

A large-scale genomic study has uncovered new genetic variations associated with multiple sclerosis (MS), findings that suggest a possible link between MS and other autoimmune diseases. The study, led by an international consortium of clinical scientists and genomics experts, is the first comprehensive study investigating the genetic basis of MS.

Researchers at the University of Chicago have found an unsuspected link between the immune system and high plasma lipid levels (cholesterol and triglycerides in the blood) in mice. The finding could l

A therapy that includes stem cell transplantation induced extended insulin independence in patients with type 1 diabetes mellitus, according to a preliminary study in the April 11 issue of JAMA.

Researchers at Stanford University have added one more trick to carbon nanotubes’ repertoire of accomplishments: a way to fight the human immunodeficiency virus (HIV). Chemistry professor Hongjie Da

When a cell has to destroy any of its organelles or protein aggregates, it envelops them in a membrane, forming an autophagosome, and then moves them to another compartment, the lysosome, for digestion.

The ebb and flow of such autoimmune diseases as multiple sclerosis, lupus and rheumatoid arthritis has long been a perplexing mystery. But new findings from the Stanford University School of Medicine

Immunologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have used nanotechnology to create a novel “biosensor” to solve in part a perplexing problem in immunology: how immune system cells called killer T-cells hunt down invading viruses.

finding by University of Pennsylvania School of Medicine researchers about how immune cells “decide” to become active or inactive may have applications in fighting cancerous tumors, autoimmune diseases, and organ transplant rejection.

Researchers from the UCLA AIDS Institute and the Institute for Stem Cell Biology and Medicine have demonstrated for the first time that human embryonic stem cells can be genetically manipulated and coaxed to develop into mature T-cells, raising hopes for a gene therapy to combat AIDS.
