Indeed, cell-mediated immunity requires that protein antigens be first degraded in the endocytic vesicles of APCs (eg, macrophages, dendritic cells), so that the smaller peptides can be presented on the cell surface by the major histocompatibility complex to activate proliferation of antigen-specific T cells
For example, the sensitization of TRPA1 with a low dose exposure to acrolein causes sensitization of TRPV1 against capsaicin.[ref] Studies in workplaces that have high VOC levels show that TRPA1 activation is the molecular initial event (MIE) leading to sensory irritation.[ref] A 2022 study investigated the sensitivity to capsaicin, a TRPV1 receptor activator, in people with MCS compared to a control group

Intranasal administration delivers the peptide efficiently to central nervous system targets, though peripheral effects on neurotrophic factor production may also benefit peripheral nerve health indirectly
