LL-37 and coronavirus variants: why results may differ
Research model: Laboratory research on viral entry
The research question
An effect against one coronavirus variant may disappear with another variant. A study on LL-37 specifically investigated that dependence on the mechanism by which the virus enters cells.
What was found?
The researchers described inhibition of a TMPRSS2-dependent step in viral entry in the variants studied, but not in the Omicron variants examined. The finding shows that a general statement about LL-37 and all SARS-CoV-2 variants is too broad.
What does this evidence mean?
This is mechanistic laboratory research, not a patient study. The result makes earlier positive observations context-dependent. The variant, model system, and entry route determine how this antiviral activity should be interpreted.
