Function

Staphylococcal enterotoxin that activates the host immune system by binding as unprocessed molecules to major histocompatibility (MHC) complex class II and T-cell receptor (TCR) molecules. In turn, waves of cellular activation, cytokine production, and migration into the lung tissue and airways occur via alphabeta T-cells.
