O-162. Immunology of human implantation

Immunology of human implantation: from the invertebrates' point of view.

Pregnancies in outbred mammals may be regarded as successfully developed homografts. One of the hypotheses that attempts to answer the enigma of why the fetus is not rejected (fetal-maternal relationships are based on reciprocal expressions of foreign transplantation antigens) claims for the existence of possible evolutionary links between invertebrate allorecognition and mammalian implantation...

Ultrastructural Modifications of Human Endometrium during the Window of Implantation

The endometrium is a highly dynamic tissue empowered with the capacity to undergo cyclic dramatic changes in response to ovarian steroid hormones, ultimately aiming to create a window of receptivity for blastocyst implantation. Intensive research has been performed to understand and establish morphological and molecular correlates of embryo implantation. However, it still remains a biological m...

Immunology of human schistosomiasis

There is a wealth of immunologic studies that have been carried out in experimental and human schistosomiasis that can be classified into three main areas: immunopathogenesis, resistance to reinfection and diagnostics. It is clear that the bulk of, if not all, morbidity due to human schistosomiasis results from immune-response-based inflammation against eggs lodged in the body, either as regula...

Determination of Superficial Clefts on Fragment of Antigen Binding in Human Immunoglobulin G by Computational Immunology

Background: Immunoglobulins (Igs) are protective glycoproteins specifically identify and eradicate microbes. Fragment of antigen binding (Fab) is a portion of antibody which binds to antigen and consists of one variable and one constant domain of one heavy and one light chain. Idiotypes, epitopes situated on Igs variable region, could be exploited to monitor and target malignant B cells and are...
