Abstract:
:An exemplar outcome of an immunology-based intervention is vaccine development; the current COVID-19 pandemic is a case in point. Can we build an immunology research ecosystem in Africa that nurtures discovery and enables translation? We see African immunologists as key agents of change and discuss obstacles and opportunities.

杂志文章,评审abstract::T cells have an amazing ability to discern and differentially respond to MHC-embedded peptides that can differ by only a single amino acid. This potential involves a combination of the precise ligand-binding specificities of the T-cell receptor (TCR) and the distinct intracellular signaling processes it transmits. Sig...
