The Evolving T Cell Receptor Recognition Code: The Rules Are More Like Guidelines.

αβ T cell receptor (TCR) recognition of peptide-MHC complexes lies at the core of adaptive immunity, balancing specificity and cross-reactivity to facilitate effective antigen discrimination. Early structural studies established basic frameworks helpful for understanding and contextualizing TCR recognition and features such as peptide specificity and MHC restriction. However, the growing TCR structural database and studies launched from structural work continue to reveal exceptions to common assumptions and simplifications derived from earlier work.

Modulation of Cell Cycle Kinases by Kaposi's Sarcoma-Associated Herpesvirus.

The cell cycle is governed by kinase activity that coordinates progression through a series of regulatory checkpoints, preventing the division of damaged cells. The Kaposi's sarcoma-associated herpesvirus (KSHV) encodes multiple genes that modulate or co-opt the activity of these kinases, shaping the cellular environment to promote viral persistence. By advancing the cell cycle, KSHV facilitates latent replication and subsequent transmission of viral genomes to daughter cells, while also contributing to the establishment of multiple cancer types.
