Role of Live Vaccines In Body's Immune Response

Researchers from Charité — Universitätsmedizin Berlin, Berlin's university hospital, have discovered a new mechanism by which live vaccines induce immunity.

Molecules produced exclusively by live microorganisms are recognized by specialized receptors of the immune system, subsequently triggering a protective immune response. The new findings may help improve the safety and efficacy of vaccines. Results from this study have been published in the journal Nature Immunology.

A Dietary Supplement Speeds Melanoma Cell Growth

According to a study, researcher determines that a dietary supplement taken to strengthen joints, i.e, Chondroitin sulfate. One particular mutation in the B-raf gene (V600E) can be found in about half of melanomas. Jing Chen, Ph.D. and colleagues found that chondroitin sulfate can boost growth by melanoma cells carrying the V600E mutation, but not other melanoma cells. The study was published in Molecular Cell.
