As evolutionary adaptation is all about living (and reproducing) in the moment, humans have evolved some unfort...

As T helper cells play critical roles in promoting antibody responses, a similar phenomenon may hold true for T helper cell responses. This concept is particularly relevant to t...

It is shown that whole-body X-irradiation, sufficient to abolish pr...
