γδ T cells were sorted from skin draining lymph nodes (CD3+ γδTCR+) or epidermis (CD45+CD3+ γδTCR+) of WT mice on Eudragit control or eRapa for 1 month using a Becton-Dickinson FACSAria II. αβ T cells were CD3+ γδ TCR. Due to low cell yield, γδ T cells were pooled from 10 mice/group. 1.5×106 cells were lysed in RIPA buffer and 15 μg protein was ran on a gel and transferred to PVDF membranes as described (6 (link)). Blots were incubated overnight at 4° C with 1:1000 diluted phospho- and/or total antibodies against indicated proteins (all Cell Signaling) plus anti-mouse β-actin (Santa Cruz Biotechnology) and detected by enhanced chemiluminescence (Pierce). Band quantification was by Image J software (National Institutes of Health).
