New publication: Mosquito viruses hijack human entry receptors through lipid adaptation
---
Mosquito-derived alphaviruses face a problem: insect and human cell membranes have different lipid compositions. Yet Chikungunya, O'nyong'nyong, and Sindbis viruses jump species efficiently anyway. A recent study reveals how they overcome this barrier by exploiting a more versatile receptor.
TIM-1 is a human immune receptor that recognises viruses by binding phosphatidylserine (PS) on viral envelopes. Mosquito-derived alphaviruses contain elevated PS and phosphatidylethanolamine (PE), both of which TIM-1 can engage. This expanded lipid recognition enhances viral entry into human cells and reveals how differences between insect and mammalian membranes influence transmission.
