Cardiopulmonary bypass is associated with postoperative humoral and cellular immune changes. Postoperative decrease in T helper (CD4), T suppressor (CD8), and B lymphocyte counts; decrease or reversal of the CD4/CD8 ratio; and poor in vitro response to mitogens have also been observed. Similar changes in lymphocyte number and function have also been noted(More)
The in vivo traffic patterns of autologous lymphocytes were studied in five normal human volunteers using lymphocytes obtained by automated apheresis, separated on Ficoll-Hypaque gradients, and labeled ex vivo with 111In-oxine. Final lymphocyte infusions contained 1.8-3.1 X 10(9) cells and 270-390 microCi (9.99-14.43 MBq) 111In, or 11-17 microCi (0.41-0.63(More)
Transfusion-associated graft-versus-host disease (TA-GVHD) may occur whenever immunologically competent allogeneic lymphocytes are transfused to an immunocompromised recipient. Irradiation of blood components eliminates the risk of TA-GVHD but may damage the cellular elements in the transfused component, particularly if the cells are stored for prolonged(More)
The premise that any bias of immune reactivity in neonatal lambs towards T-helper (TH)2 responses could benefit the induction of protection against gastrointestinal nematodes was investigated. In two trials, lambs were either trickle-immunised with 2000 infective larvae of Trichostrongylus colubriformis (TcL3), 3 times weekly from the day of birth for 6(More)
In two trials, lambs were trickle infected with 400 or 1000 infective larvae of Haemonchus contortus (HcL(3)), twice weekly for 4 weeks from the day of birth. Following anthelminthic treatment at 6 weeks (Trial 1) or 7 weeks of age (Trial 2), lambs were challenged 1 week later with a trickle infection totalling 5000 (Trial 1) or 10000 HcL(3) (Trial 2).

The J558L cell line, previously transfected with the ovine Cepsilon gene, was induced to secrete a chimeric IgE protein composed of the ovine heavy chain and a mouse light chain with MW of approximately 80 and 26 kDa, respectively. After purification, the chimeric protein was used to immunise BALB-c mice and monoclonal antibodies (mAbs) were generated. The(More)
