Immune system stimulation via mucosal and systemic pathways

The term "Immune system stimulation via mucosal and systemic pathways" refers to strategies aimed at activating or enhancing immune responses at both mucosal surfaces (such as the gastrointestinal, respiratory, or genitourinary tracts) and throughout the whole body (systemically). Immunologically, this involves various families of molecules, including pattern recognition receptors (such as Toll-like receptors (TLRs)[2][6], NOD-like receptors (NLRs)[3][7], and C-type lectin receptors), cytokines, and cellular effectors in both the innate and adaptive immune systems[1][2][7]. These pathways are relevant to the development of vaccines, mucosal adjuvants, and immunotherapies, but do not describe a discrete therapeutic target. Since this entry is not a single molecule, gene, or drug target, but rather refers to a multifaceted physiological or immunopharmacological concept, it is unsuitable as a canonical molecular target entry.
