To analyze their T cell stimulatory capabilities, we incubated splenocytes of Art v 1‐specific TCR/DR1 allergy mice with MA::Art v 1 VNP, Art v 1::GPI VNP, empty VNP (10 μg/mL), or rArt v 1 (0.5 μg/mL) and compared them to cultures supplemented with either medium alone or PMA plus ionomycin, respectively. The gene discussed is DR1; the disease is allergic disease.
