[The protective effect of molsidomin in immune ovarian pathology in mice]
Abstract:
Experimental immune ovarian failure in CBA mice was induced by either administration of xenogenic anti-ovarian antibodies (scheme 1) or immunization with allogenic ovarian extracts (scheme 2). It was shown that both types of treatment impaired the meiotic maturation of oocytes: the number of cells at the stages of metaphase I and metaphase II decreased compared to the cells of control mice. In both schemes of experiments, impaired oogenesis was accompanied by reduction of percentage of viable follicular cells and by increase in the part of cells possessing morphological features of apoptosis. In contrast, the number of necrotic follicular cells increased in scheme 2 only. The donor of nitric oxide molsidomin (10 mg/ kg), when injected an hour before administration of xenogenic anti-ovarian antibodies or allogenic ovary extracts, improved the meiotic maturation of oocytes and favored follicular, lymph nodes and thymus cells survival by decreasing the number of apoptotic and necrotic cells.
Insights
Experimental immune ovarian failure in mice impairs oocyte maturation and follicular cell survival. Molsidomin, a nitric oxide donor, protected against these effects, improving oocyte quality and cell viability.
Area of Science:
- Immunology
- Reproductive Biology
- Cell Biology
Context:
- Immune-mediated ovarian failure is a significant concern in reproductive health.
- Understanding the cellular mechanisms of ovarian damage is crucial for developing therapeutic strategies.
- Ovarian failure can be induced experimentally to study its pathogenesis.
Purpose:
- To investigate the effects of experimental immune ovarian failure on oocyte meiotic maturation and follicular cell viability in mice.
- To evaluate the protective role of molsidomin, a nitric oxide donor, against immune-induced ovarian damage.
Summary:
- Experimental immune ovarian failure was induced in mice using anti-ovarian antibodies or ovarian extracts.
- Both methods impaired oocyte meiotic maturation (metaphase I and II) and reduced viable follicular cells, increasing apoptosis.
- Molsidomin administration protected against these effects, improving oocyte maturation and cell survival by reducing apoptosis and necrosis.
Impact:
- This study highlights the detrimental effects of immune-induced ovarian failure on oogenesis and follicular cell health.
- Molsidomin demonstrates potential as a protective agent against immune-mediated ovarian damage.
- Findings contribute to understanding the role of nitric oxide in reproductive organ protection and immune responses.
