Maternal and genetic factors determine early life telomere length.
In a broad range of species--including humans--it has been demonstrated that telomere length declines throughout life and that it may be involved in cell and organismal senescence. This potential link to ageing and thus to fitness has triggered recent interest in understanding how variation in telomere length is inherited and maintained. However, previous studies suffer from two main drawbacks ...
متن کاملEcological and life-history factors influencing the evolution of maternal antibody allocation: a phylogenetic comparison.
Maternally derived yolk antibodies provide neonates with immune protection in early life at negligible cost to mothers. However, developmental effects on the neonate's future immunity are potentially costly and thus could limit yolk antibody deposition. The benefits to neonatal immunity must be balanced against costs, which may depend on neonate vulnerability to pathogens, developmental traject...
متن کاملInhibition of PHA-induced lymphocyte stimulation by factors in maternal serum during late pregnancy.
Immunosuppressive effect of pregnant serum obtained in the second and third trimesters was demonstrated in the PHA-induced homologous lymphocyte stimulation system, where 3H-thymidine incorporation into DNA was measured. Such an inhibitory factor was not present in the first trimester serum. The immunosuppressive principle detected in the second trimester serum was characterized by a potent inh...
متن کاملEarly history of specific antibody-producing lymphocyte hybridomas.
Specific antibody-producing lymphocyte hybridomas have become a major tool of research in tumor immunology. The production of monoclonal antibodies by lymphocyte hybrido mas in vitro or in ascites fluid in vivo dates from the experiments of Kohler and Milstein (2), followed closely by many others. The purpose of this correspondence is to direct attention to tetraploid murine lymphoma cell lines...
متن کاملEarly Events in Lymphocyte Transformation by Phytohemagglutinin
The DNA-dependent RNA polymerase activities of isolated nuclei from lymphocytes were examined after stimulation with phytohemagglutinin (PHA). The nuclear fraction was prepared with Mg(++) or Mn(++) to distinguish between polymerase I (nucleolar) and polymerase II (nucleoplasmic). Distinction between polymerases II and III was obtained by the addition of alpha-amanitin to the reaction mixture. ...
