Autonomic nervous system appears to function well regardless of mode of childbirth

Late in pregnancy, the human body carefully prepares fetuses for the rigors of life outside the protection of the womb. Levels of cortisol, a stress hormone, ramp up and spike during labor. Catecholamines, another stress hormone, also rise at birth, helping to kick start the necessary functions that the baby will need to regulate breathing, heartbeat, blood pressure and energy […]

Holes in the immune system left unrepaired despite drug therapy

If they don’t receive antiretroviral therapy (ART), most HIV patients see a progressive weakening of their immune system. But a very small percentage of patients—0.3%—spontaneously control the virus themselves, without ART.

One reason TB is so pervasive is that treatment requires a six-month course of daily antibiotics, which is difficult for about half of all patients to adhere to, especially in […]

Self-destruction system in TB bacteria may lead to ‘perfect drug’

Doctors and molecular engineers working to enlist the immune system to fight cancer

When telling the story of immunotherapy and cancer and how the two battle it out, it’s awfully challenging not to pull out the old A Tale of Two Cities cliché. Because everyone agrees: It is the best of times in cancer research and treatment. Over the past five years, the standard of care for treatment of many cancers has made […]
