CD4 and asthma: To assess whether adoptively transferred CD4+ T cells from sensitized wildtype mice, where all three selectins are in place, could reverse the non-development of asthma phenotype in ELP-/- mice, adoptive transfer of the aforementioned cells from spleen of senstitized WT mice were transferred by tail vein injection to naïve ELP-/- mice followed by OVA challenge as described in Materials and Methods.
