Naturally endemic infectious diseases provide selective pressures for pig populations. Toll-like receptors (TLRs) represent the first line of immune defense against pathogens are are likely to play a crucial adaptive role for pig populations. Dr. Darfour-Oduro led a study to determine whether wild and domestic pig populations representing diverse global environments demonstrate local TLR adaptation. The results were recently published in Immuogenetics.
