A key antibody, IgG, links cells' capture and disposal of germs
Scientists have found a new task managed by the antibody that's the workhorse of the human immune system: Inside cells, Immunoglobulin G (IgG) helps bring together the phagosomes that corral invading pathogens and the potent lysosomes that eventually kill off the germs.   view more (2006-11-14)

New, more direct pathways from outside the cell-to-cell nuclei discovered
A team of Brooklyn College researchers has shattered a long-held belief that no direct pathway exists between material outside of a cell and the cell nucleus. (The cell is the smallest metabolically functional unit of life.)   view more (2007-08-13)

Proteomics Study Yields Clues As To How Tuberculosis Might Be Thwarting The Immune System
A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.   view more (2008-11-06)

Novel tuberculosis vaccine in Germany in clinical phase
For the first time in more than 80 years a promising live vaccine against tuberculosis has passed into the clinical phase in Germany: Since Monday of this week the new vaccine, which goes by the designation "VPM1002", has begun safety testing on volunteers in a Phase I clinical trial in... view more (2008-09-12)

St. Jude finds link between cellular defense processes, showing how cancer cells survive
St. Jude Children's Research Hospital investigators have discovered that immune system cells that engulf and destroy germs in the body enlist help for this task from a common housekeeping mechanism that most cells use to keep their interiors healthy, a finding that is likely to help researchers... view more (2007-12-20)
