Academic Background γδ T cells are a unique subset of the immune system, characterized by T cell receptors (TCRs) composed of γ and δ chains that recognize non-peptide antigens, such as phosphoantigens (PAgs) produced by microbial or tumor cells. Among them, Vγ9Vδ2 T cells are the most abundant γδ T cell subset in human circulation and play a criti...

Academic Background Proton transfer plays a central role in biological energy conversion (e.g., ATP synthesis) and signal transduction. Traditional theory posits that protons move via a “hopping mechanism” through water chains or amino acid side chains, while the recently proposed “proton-coupled electron transfer” (PCET) hypothesis suggests that e...
