A specific and sensitive homologous radioimmunoassay (RIA) for determination of hamster prolactin is described and compared to heterologous hamster prolactin RIA and to the homologous and heterologous RIAs for rat prolactin. With this method, we have determined that, in the golden hamster, diurnal plasma prolactin fluctuations have a mean interpeak interval(More)
Prepubertal girls and gonadotropin-releasing hormone (GnRH)-deficient females secrete follicle-stimulating hormone (FSH) preferentially in response to intravenous GnRH. With continued pulsatile GnRH stimulation, FSH secretion is reduced when plasma estradiol (E2) is increasing. To delineate the mechanisms involved in these changing gonadotropin responses, e(More)
Summary: Fourteen children between 2.5 and 16 years of age were studied to provide a quantitative estimate of the changes in gonadotropin-releasing hormone (GnRH) pulse amplitude in hypophysial portal plasma during puberty. Responses to physiologic doses of synthetic GnRH were measured [induced luteinizing hormone (ΔLH) and induced follicle-stimulating(More)
Patients with isolated gonadotropin deficiency were studied to determine whether pulsatile low dose gonadotropin-releasing hormone (GnRH) could induce the hormonal changes seen during normal puberty. Four male and two female patients with immature responses to a standard GnRH test (2.5 micrograms/kg) were given GnRH (0.025 micrograms/kg) iv every 2 h for 5(More)
Type 1A diabetes (T1D) is believed to be caused by immune-mediated destruction of β-cells, but the immunological basis for T1D remains controversial. Microbial diversity promotes the maturation and activation of certain immune subsets, including CD161 bright CD8+ mucosal associated invariant T (MAIT) cells, and alterations in gut mucosal responses have been(More)
Type 1 diabetes (T1D) is a chronic disease characterized by autoimmune-mediated destruction of pancreatic insulin-producing beta cells. Interleukin (IL)-18 is a pro-inflammatory cytokine implicated in the pathogenesis of a number of inflammatory diseases. Here, we analyzed IL-18 levels in the plasma of juveniles with T1D. Compared to control subjects, IL-18(More)
Type 1 diabetes (T1D) is a chronic disease caused by autoimmune destruction of insulin-producing pancreatic β-cells. T1D is typically diagnosed in children, but information regarding immune cell subsets in juveniles with T1D is scarce. Therefore, we studied various lymphocytic populations found in the peripheral blood of juveniles with T1D compared to(More)
