Early Activation of Immune Response Could Lead to Better Vaccines

Albert Einstein College of Medicine

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a new “first response” mechanism that the immune system uses to respond to infection. The findings challenge the current understanding of immunity and could lead to new strategies for boosting effectiveness of all vaccines. The study, conducted in mice, published online today in the journal Immunity.

Protein Found to Regulate Red Blood Cell Size and Number

Whitehead Institute for Biomedical Research

By examining the results of genome-wide association studies (GWAS) in conjunction with experiments on mouse and human red blood cells, researchers in the lab of Whitehead Institute Founding Member Harvey Lodish have identified the protein cyclin D3 as regulating the number of cell divisions RBC progenitors undergo, which ultimately affects the resulting size and quantity of RBCs.
