The second immune system category is adaptive B cell immunity, a slower response that creates powerful, pathogen-specific antibodies and provides lasting immunity. The body's normal response to infection is to produ...

Antibiotic might fight HIV-induced neurological problems

...the infection seems to be controlled, it may still cause damage in the brain. And because people are living with HIV longer than ever, the prevalence of neurological damage is increasing. Currently, there's no drug to treat it directly." In use for more than 30 years, minocycline was specifically designed...
