title: Effect of amino acids and antibodies against nerve growth factor receptors on the development of organotypic culture of lymphoid tissue.
abstract: We studied the effects of 20 L-amino acids on organotypic culture of splenic lymphoid tissue from 3-month-old rats were studied in the presence of apoptosis-inducing monoclonal antibodies against low-affinity receptors for nerve growth factor NGFRp75. The influence of amino acids stimulating cell proliferation in explants (lysine, asparagine, and glutamic acid) did not depend on NGFRp75. Hydrophobic amino acids inhibiting the growth zone in isolated application and abolished the inhibition of explant development in the presence of antibodies against NGFRp75. These amino acids can mediate the proapoptotic effect on lymphoid tissue via low-affinity receptors for nerve growth factor.
