Programmed death and the identification of growth factors delaying this process in the oligodendrocyte lineage suggest that other cell types provide oligodendrogliotrophins. To determine their source, primary cultures of oligodendroblasts immunopurified from postnatal rat cerebrum were used to screen other cultured neural and non-neural cell types for the release of survival factors into a defi...
A monospecific inhibitory antibody directed to phospholipase C (phosphoinositidase C) blocked the antiviral effect of human interferons alpha and beta when tested on human quiescent fibroblasts challenged with the vesicular stomatitis virus. This action was due to specific inhibition of polyphosphoinositide hydrolysis because (a) the F(ab')2 fragment of the antibody molecule was also inhibitory...
Neurotransmitter uptake into synaptic vesicles is mediated by vesicular neurotransmitter transporters. Although these transporters belong to different families, they all are thought to share a common overall topology with an even number of transmembrane domains. Using epitope-specific antibodies and mass spectrometry we show that the vesicular GABA transporter (VGAT) possesses an uneven number ...
Monoclonal antibodies against soybean Bowman-Birk protease inhibitor (BBI) have been generated and used to detect and quantify BBI in foods, soybean germplasm, and animal tissues and fluids. The purpose of this study was to determine the recognition sites of two monoclonal antibodies to BBI (mAb 238 and mAb 217) in relation to the protease-inhibitory sites of BBI. The results showed that (1) th...
Incorporation of asparagine synthetase-specific monoclonal antibodies into L5178Y D10/R (L-asparaginase-resistant) murine lymphoma cells by osmotic lysis of pinocytic vesicles was used to evaluate the potential of the technique for macromolecular incorporation for metabolic studies. Nonspecific effects of the incorporation procedure included temporary inhibition of protein and DNA synthesis by ...
Invasion of erythrocytes by Plasmodial merozoites is a composite process involving the interplay of several proteins. Among them, the Plasmodium falciparum Cysteine-Rich Protective Antigen (PfCyRPA) is a crucial component of a ternary complex, including Reticulocyte binding-like Homologous protein 5 (PfRH5) and the RH5-interacting protein (PfRipr), essential for erythrocyte invasion. Here, we p...
