Immune research in this area centres on the thymus, the gland where T cells mature and which shrinks steadily from childhood onward. Several compounds are peptides isolated from or modelled on thymic tissue, studied for whether they influence immune signalling in older animals and people.
The category also includes antimicrobial peptides — short sequences the body produces as a first line of defence — and compounds studied for their effect on inflammatory pathways.
