Anti-inflammation genes linked to longer lives

Species with more ‘Siglecs’ get longevity boost, study suggests

Siglec genes

LONGEVITY BY THE NUMBERS  How long a species lives depends upon the number of “Siglec” genes it carries. Siglec genes encode immune proteins that may protect against aging by fighting oxidants. Source: Schwarz et al./eLife 2015; Adapted by E. Otwel.

Stocking up on genes that help control inflammation leads to longer life spans for humans and other species, a new study suggests.
