T cell adhesion to HPMCs after exposure to PYS or to HPG for 7 days. A monolayer of HPMCs after treatment with PYS or HPG for 7 days was co-cultured with an equal number of Jurkat T cells for 48 h. a Imaging data were presented as a typical microscopic view of adhesive T cells, indicated by small size and spherical in shape in each group. b Data were presented as mean ± SD of ten separate experiments (n = 10). p = 0.0002 (PYS vs. HPG, t-test). *p < 0.0011 (PYS vs. Untreated, t-test). **p < 0.0011 (HPG vs. Untreated, t-test)
