Deadly Bacteria Stiff-Arm the Immune System
The most severe strep infections are often the work of one strain known as M1T1, named for the type of tentacle-like M protein projecting from the bacterium’s surface. Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences have uncovered a new way M1 contributes to strep virulence — the protein’s ability to hold off antimicrobial peptides. The study is published October 14 by Cell Host & Microbe.
