Expansion of CD4(+) CD25(+) and CD25(-) T-Bet, GATA-3, Foxp3 and RORγt cells in allergic inflammation, local lung distribution and chemokine gene expression.
We conclude that eosinophil and neutrophil migration into the air space in allergic lung inflammation is partially CD18 (beta2)- and CD49d (alpha4)- dependent and that alpha4 integrins mediate essentially all of the CD18-independent migration.
