The peptide alpha-melanocyte-stimulating hormone (alpha-MSH) occurs within the pituitary, brain, skin, ovary and other tissues, and has potent anti-inflammatory activity. For this reason, we examined its effects on an autoimmune disease: the experimental autoimmune-oophoritis (EAO). We analyzed the
We studied the effect of alpha-melanotropin hormone (alpha-MSH) on experimental autoimmune oophoritis (EAO), an inflammatory process induced in female rats. During proestrus, serum levels of LH and progesterone in rats with EAO were higher than those of control rats. However, administration of
A woman with autoimmune oophoritis was found to have luteal phase progesterone levels throughout a six-month period of amenorrhea. The common presentation of amenorrhea or metrorrhagia, despite the presence of a corpus luteum, in women with autoimmune oophoritis might result from this chronic
Interactions between the immune and endocrine systems may have an important role in ovarian tumorigenesis. Neonatal thymectomy at 3 days of age (Tx-3) in (C3H/HeMs x 129/J)F1 (C31) female mice results in an autoimmune ovarian dysgenesis then subsequent tumor formation. At 3 months of age the
Two experiments (Experiment I, n=12 Holstein-Friesian heifers; Experiment II, n=8 Jersey cows) were conducted to investigate the pathogenesis of bovine pestivirus-induced ovarian dysfunction in cattle. In both experiments the cattle were superovulated with twice daily injections of a porcine
Oophoritis, a complication of mumps, is said to affect only 5% of all postpubertal women. In this report, we present a case of a 31-year-old Iranian woman with amenorrhea and infertility due to an infantile uterus and atrophic ovaries associated with contracting mumps at a young age. In conclusion, a complete workup of the bitch that has not shown a puberal estrus by 24 months of age should include a general screen with hemogram, chemistries profile and urinalysis, karyotype, serum thyroid hormone profile, serum progesterone concentration, and serum luteinizing hormone
Zona pellucida (ZP) glycoproteins are promising candidate antigens for use in immunocontraceptive vaccines because of their crucial role in mammalian fertilization. A single intraperitoneal immunization with recombinant murine cytomegalovirus engineered to express murine ZP3 (rMCMV-mZP3) induces
There is no known immunosuppressive therapy for autoimmune premature ovarian failure that has been proven safe and effective by prospective randomized placebo-controlled study. Nevertheless, immunosuppression using corticosteroids has been used on an empirical basis for this condition. Here we
C3H/HeN female mice infected with distinct Trypanosoma cruzi subpopulations (RA strain [pantropic/reticulotropic] and K98 clone of the CA-I strain [myotropic]) show differences both in inflammatory compromise of the genital tract and in the outcome of pregnancy. The group of mice infected with the
Autoimmune Regulator (AIRE) regulates central immune tolerance by inducing expression of tissue-restricted antigens in thymic medullary epithelial cells, thereby ensuring elimination of autoreactive T cells. Aire mutations in humans and targeted Aire deletion in mice result in multiorgan autoimmune
