Putting the brakes on immune reactions

When we are exposed to a pathogen, the immune system’s B cells swarm to our lymph nodes, spleens, and tonsils. There, those cells mutate in germinal centers—microscopic boot camps that rush the B cells through volleys of mutations to produce the most potent antibodies for neutralizing the infectious agent. As […]

Hunting for TB's most vulnerable genes

Developing drugs to combat tuberculosis, or TB, can be frustrating business. A gene essential to the bacteria’s lifecycle is discovered, scientists rush to develop drugs that inhibit the target, and then—disappointment. Volleys of compounds hurled at the essential gene target have little impact on microbial growth. The bacteria live on. […]
