Low plasma levels of decoy receptor 3 (DcR3) in the third trimester of pregnancy with preeclampsia.

Objective: The pathophysiology of preeclampsia, a major threat during pregnancy characterized by excessive inflammatory status, remains unclear. Decoy receptor 3 (DcR3), a soluble member of the tumor necrosis factor receptor (TNFR) superfamily, is capable of inducing anti-apoptosis via binding with TL1A and anti-inflammation by driving Th2 immune reactions. DcR3 may, therefore, play a role in immune modulation during pregnancy.

Gastrointestinal stromal tumor presenting as a rectovaginal septal mass: A case report and review of literature.

Introduction: Gastrointestinal stromal tumors (GISTs) arising from the gynecological tract are extremely rare. A case of GIST with an unusual presentation as a vaginal mass is presented with comprehensive literature review, aiming to gain a better understanding of the diagnostic and treatment strategy of the disease.

Patient Concerns: A 78-year-old woman presented with persistent vaginal bleeding and difficulty in micturition.

CD28 plays a critical role in the segregation of PKC theta within the immunologic synapse.

The signaling pathways that lead to the localization of cellular protein to the area of interaction between T cell and antigen-presenting cell and the mechanism by which these molecules are further sorted to the peripheral supramolecular activation cluster or central supramolecular activation cluster regions of the immunologic synapse are poorly understood. In this study, we investigated the functional involvement of CD28 costimulation in the T cell receptor (TCR)-mediated immunologic synapse formation with respect to protein kinase C (PKC)theta; localization. We showed that CD3 crosslinking alone was sufficient to induce PKC theta; capping in naive CD4(+) T cells.
