TL;DR: A new preprint explores the mosquito sialome (saliva proteome), showing how its proteins act as anticoagulants, immune modulators, and even pain suppressors. Beyond vector biology, these molecules could inspire vaccines against mosquito-borne diseases and novel therapeutics (anti-inflammatory, antiviral, non-opioid analgesics, anticoagulants). Early-stage research, but intriguing biotech potential.
