Antifungal Immune Response

By | June 3, 2011

For years researchers believed that any effective antifungal vaccine would have to induce the production of antibodies.  Research studies have now shown that the cellular immune responses mediated by Th1 and Th17 cytokines are just as important.

Epigenetic Changes in Cancer

By | March 1, 2011

In cancer cells the epigenetic landscape is highly altered. Hypermethylation of certain stretches of DNA is the most well-studied epigenetic modification in cancer, and each tumor type has its own specific pattern. Histone modifications also occur, a
