Many chemical mediators are found in body fluids such as sebum, saliva, mucus, gastric and intestinal fluids, urine, tears, cerumen, and vaginal secretions. Antimicrobial peptides (AMPs) found on the skin and in other areas of the body are largely produced in response to the presence of pathogens. These include dermcidin, cathelicidin, defensins, histatins, and bacteriocins.

It highlights their various mechanisms of action against bacteria, fungi, and viruses. Additionally, it mentions antimicrobial proteins in plasma, particularly acute-phase proteins like C-reactive protein and ferritin, which are vital for the innate immune response and aid in inhibiting pathogen growth and promoting phagocytosis.

They operate through autocrine, paracrine, or endocrine signaling. Key classes include interleukins, chemokines, and interferons, each playing specific roles in immune modulation and infection response.
