B8, DR3 antigens and production of human leucocyte migration inhibitory factor (LIF) by mononuclear cells stimulated with concanavalin A (Con A)

2008

LIF release by Con A stimulated mononuclear cells was evaluated in 67 randomly selected healthy Sicilians typed for HLA antigens. The results show that B8 and/or DR3 positive subjects release less LIF than negative ones, suggesting that this immunological response might be controlled by HLA-linked immune response (Ir) gene(s).

Delayed-type skin reactions in bursectomized or thymectomized chickens.

1977

Chickens can easily be induced to develop delayed-type skin reactions to oxazolone when animals are sensitized 7 days before the challenge. The reaction is quantitated by assessing the increase in wattle thickness: maximum reactions occur 24 h after challenge. The reaction is inhibited by neonatal thymectomy or bursectomy; these findings therefore suggest also an important B-derived component in delayed hypersensitivity to oxazolone.
