Inherited paternal HLA antigens from the semi-allogeneic fetus may trigger maternal immune responses during pregnancy, leading to the production of child-specific HLA antibodies. The prevalence of these HLA antibodies increases with the number of successful pregnancies. In the present study, we investigated the effect of a single prior miscarriage on HLA antibody formation during a subsequent s...

The genes that code for the human major histocompatibility class I antigens, HLA-A2 and HLA-B7, were introduced into human, monkey, and mouse cell lines by cotransfection with suitable biochemical markers and the fluorescence-activated cell sorter was used to identify and/or select stable cell populations expressing high surface levels of these antigens. Levels of expression obtained were simil...

HLAMatchmaker is a computer algorithm that assesses human leukocyte antigen (HLA) compatibility at the structural level by intralocus and interlocus comparisons of polymorphic amino acid triplets in antibody-accessible sequences of HLA class I molecules. This program permits the identification of mismatched HLA antigens that share all of their polymorphic triplets with the patient's HLA antigen...

Background: The origin and function of human leukocyte antigen (HLA) class I molecules on platelets are still highly arguable. Given the differences in the results of the previous studies in this regard, the lack of research in recent years, and the clinical importance of HLA class I molecules, the absorption capacity of platelets for soluble HLA class I molecules was studied in this investigat...

Understanding of the relationship between tumor infiltrating cytotoxic T lymphocytes (CD 8(+)TILs) and tumor cells as well as tumor-associated antigens is important and may reflect the extent of immune response of the patient to the tumor, thus providing a useful clue relevant to the prognosis. The purpose of this study was to determine the relationship between the expression of HLA-DR and CA-1...

This study defines 10 epitopes by murine monoclonal antibodies, of which seven are new and three were previously defined by alloantibodies. Of particular interest, three antibodies reacted with almost all Bw4-associated antigens except that each was negative with one or two of the antigens. One was negative with B13, one negative with A25, and another negative with B13 & A24 antigens. These mon...
