Mice lacking key immune component still control chronic viral infections

... enable an active immune response to other chronic infectious agents. Some current efforts to develop antiviral vaccines focus exclusively on portions of viral proteins likely to be picked up and presented by MHC Class I molecules. If these backup mechanisms are important to control of herpes and other chroni...

Human behavior changes the number of strains of infectious diseases

Simple models predict that only one strain of an infectious disease can exist at one time, but observation sug...researchers found that the coexistence of multiple infectious disease strains result from monogamous populations. "When people are serially monogamous (that is,...

First human study confirms that immune cells can be a primary cause of bone loss in gum disease

...riodontal disease very distinct from other chronic infectious diseases. B cells are known to produce a weapon (antibody) that normally attacks bacteria and protects our body from bacterial infection. As a consequence of dense infiltration of B cells found in the gum, periodontally diseased patients mount signif...

It starts with bacteria, which are cloaked by an outer membrane--a defensive barrier against the harsh elements of their environment, whether toxins in nature or the pr...

How HIV 'exhausts' killer T cells

"What we have now discovered is that these stem cells have a sort of antennae that detect bacteria and viruses," continued the OMRF researcher.

When antibiotics are mixed with fish food, residual antibiotics may be found in fish products and fish meat. People who eat these products will be inadvertently consuming antibiotics, leading to changes in ...
