Antigen-driven TCR signaling in the epidermis during CD8+ TRM differentiation results in a lower TGFβ requirement for persistence and increased proliferative capacity that together enhance epidermal TRM fitness.
The stability of ribonucleoprotein complexes of SARS-CoV-2 nucleocapsid proteins differs among variants of concern and the viral evolution of nucleocapsid protein can be understood in the framework of fuzzy complexes.
