Summary image of the article. The upper part highlights neuronal cell cycle re-engagement is a stage proceeding neuronal senescence and that their full molecular profiles can now be identified by the ...

For decades, dogma dictated that the immune system consisted of two separate branches. Cells of the innate system respond rapidly to molecular patterns shared by a broad array of pathogens. Meanwhile, ...

However, details of the intervening steps, as researchers have learned in the past 65 years, are quite complex — certain cells carry the flu antigen to the immune system, specific immune cells respond ...

The awe-inspiring process of cell division can turn a fertilized egg into a baby -- or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process ...

Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study. The phenomenon may ...

T-bet expression is required for persistence of memory B cells that have rapid differentiation potential to become antibody-producing plasma cells in response to a second infection BIRMINGHAM, Ala. – ...
