Case Report: Uterine Didelphys and Cervical Agenesis in an 18 Year-Old Woman Presenting with a Pelvic Mass.

Background: Although Müllerian anomalies are relatively common they can be easily misdiagnosed as other gynecologic conditions leading to inappropriate treatment.

Case: An 18-year-old woman presented to the hospital with abdominal pain and was found to have a 17-cm pelvic mass and absence of the cervix. Because of concern for recurrent endometrioma formation in the setting of a Müllerian anomaly, she underwent a hysterectomy.

Hepatitis C Virus Sensing by Human Trophoblasts Induces Innate Immune Responses and Recruitment of Maternal NK Cells: Potential Implications for Limiting Vertical Transmission.

Hepatitis C virus (HCV) is the world's most common blood-borne viral infection for which there is no vaccine. The rates of vertical transmission range between 3 and 6% with odds 90% higher in the presence of HIV coinfection. Prevention of vertical transmission is not possible because of lack of an approved therapy for use in pregnancy or an effective vaccine.

Minor histocompatibility antigens and the maternal immune response to the fetus during pregnancy.

The tolerance of the semiallogeneic fetus by the maternal immune system is an important area of research for understanding how the maternal and fetal systems interact during pregnancy to ensure a successful outcome. Several lines of research reveal that the maternal immune system can recognize and respond to fetal minor histocompatibility antigens during pregnancy. Reactions to these antigens arise because of allelic differences between the mother and fetus and have been shown more broadly to play an important role in mediating transplantation outcomes.

Minor histocompatibility antigens are expressed in syncytiotrophoblast and trophoblast debris: implications for maternal alloreactivity to the fetus.

The fetal semi-allograft can induce expansion and tolerance of antigen-specific maternal T and B cells through paternally inherited major histocompatibility complex and minor histocompatibility antigens (mHAgs). The effects of these antigens have important consequences on the maternal immune system both during and long after pregnancy. Herein, we investigate the possibility that the placental syncytiotrophoblast and deported trophoblastic debris serve as sources of fetal mHAgs.

Moderate influence of human APOBEC3F on HIV-1 replication in primary lymphocytes.

Multiple APOBEC3 proteins are expressed in HIV-1 target cells, but their individual contributions to viral suppression when expressed at endogenous levels remain largely unknown. We used an HIV NL4-3 mutant that selectively counteracts APOBEC3G (A3G) but not APOBEC3F (A3F) to dissect the relative contribution of A3F to the inhibition of HIV-1 replication in primary human lymphocytes (peripheral blood mononuclear cells [PBMCs]). This HIV Vif mutant replicated similarly to wild-type virus in PBMCs, suggesting that the effect of A3F on HIV restriction in these cells is limited.
