    Abstract We have investigated the effect of exogenous IL-7 on replication of HIV-1 in PBMCs isolated from asymptomatic, chronically infected donors. We show that IL-7 induced virus replication and increased proviral DNA levels in CD8- PBMC cultures. IL-7 also increased the levels of doubly spliced HIV-1 tat RNA in these cultures. In comparison, IL-2 induced lower levels of virus production than IL-7, but had a more pronounced effect on cell proliferation. The IL-7-mediated increase in virus replication was not inhibited by neutralizing mAbs to IL-1 beta, IL-2, IL-6, or TNF-alpha, and was only partially dependent on ligation of the T cell accessory molecule CD28. CD8+ cells inhibited the increase in viral replication following IL-7 stimulation, but did not prevent virus replication following ligation of CD3 in the presence of IL-7. The data shows that IL-7 regulates HIV-1 replication in naturally infected PBMCs.

    Abstract The increases in firing rates of hippocampal cells were examined following microiontophoretic application of several muscarinic cholinergic receptor agonists. The agonists studied had been pharmacologically characterized previously and divided into two classes: class A agonists (e.g. acetylcholine, carbamylcholine, and oxotremorine-M) which maximally stimulate PI turnover and reveal mAChR heterogeneity, and class B agonists (e.g. bethanecol and oxotremorine-1) which poorly stimulate PI turnover and do not alter mAChR conformation/orientation in the hippocampus. While comparable stimulatory effects on hippocampal pyramidal cell firing rates were seen with both classes of agonists during short (20 s) ejection periods, longer applications (greater than 25 s) produced class-dependent differential firing patterns. Prolonged ejection of class A agonists selectively desensitized cells to further, continued application in the same ejection period, and the firing rates declined. Class B agonists produced stimulatory responses in hippocampal cells during the entire ejection period, and DE was not observed. This desensitization effect (DE) was observed only for bursts and not for simple spikes.
