SWAP-70?/? mice primed with IgE and challenged with DNP-KLH, demonstrated only a little decrease in body’s temperature to about 35 C and an instant recovery, indicating a solid decrease in the systemic anaphylactic response induced by FcRI
SWAP-70?/? mice primed with IgE and challenged with DNP-KLH, demonstrated only a little decrease in body's temperature to about 35 C and an instant recovery, indicating a solid decrease in the systemic anaphylactic response induced by FcRI. Since mature peritoneal mast cells usually do not express SWAP-70 [2], we asked which types of mature tissues mast cells express SWAP-70. intravenous shots from the antigen DNP-BSA with 0.5 % Evans blue into wt or SWAP-70 deficient mice which were sensitized by intradermal ear injections your day before with IgE in HBBS (still left ear) or HBSS alone (right ear). Extravasation from the dye is certainly due to histamine and serotonin discharge from FcRI-activated mast cells [32] as well as the dye accumulates in the tissues. 30 min after antigen excitement the…
