Effector functions and proliferation of T helper (Th) cells are influenced by cytokines in the environment. Th1 cells respond to a synergistic effect of interleukin-12 (IL-12) and interleukin-18 (IL-18) to secrete interferon-gamma (IFN-gamma). In contrast, Th2 cells respond to interleukin-4 (IL-4) to secrete IL-4, interleukin-13 (IL-13), interleukin-5(More)
Oocyte maturation is controlled by a combination of hormonal and local follicular factors. Osmolarity, pH, and perhaps Ca2+ concentration of the surrounding medium are also important. Follicular fluid contains a low molecular weight OMI which acts to keep the oocyte from maturing. Luteinizing hormone added to cultured cumulus enclosed porcine oocytes can(More)
