Peripheral Regulatory T Cells Take the Road Less Traveled

T cells serve as key weapons in the mammalian immune system’s arsenal, defending the host against invading pathogens such as bacteria and viruses. But sometimes these powerful weapons attack host tissues, wreaking havoc in the form of autoimmune diseases like lupus erythematosus and multiple sclerosis.

This review will focus on recent studies that have identified bacterial proteins and host processes that play a concerted role in trans...

This challenge stems from the most recent encouraging reports of a success rate of over 15 years of implant therapy to treat partial edentulism. The main criticism of traditional periodontal therapy targ...
