SummaryThe platelet proteins of 9 thrombasthenic patients from 7 families were analysed by high resolution two-dimensional gel electrophoresis (HR-2DE) and crossed immunoelectrophoresis (CIE). In 7 patients both glycoproteins (GPs) IIb and Ilia were absent or reduced to roughly the same extent. In two related patients only a trace of GP Ilb-IIIa complex was detected in CIE, but HR-2DE revealed a glycopeptide in the position of GP Ilia in an amount comparable to type II thrombasthenia. This GP Ilia-like component was neither recognized normally by anti-GP Ilb-IIIa antibodies nor labeled by surface iodination. In unreduced-reduced two-dimensional gel electrophoresis two components were observed in the region of GP Ilia. The assumption of a structural variant of GP Ilia in the two related patients is discussed.

Background: Polycystic ovary syndrome (PCOS) is the most frequent endocrine disorder affecting 6–7% of premenopausal women. Recent studies revealed that the immune system especially CD4+ T helper cells are important in the context PCOS. Proteome analysis of CD4+ T lymphocytes can provide valuable information regarding the biology of these cells in the context of PCOS. Objective: To investigate immune dysregulation in CD4+ T lymphocytes at the protein level in the context of PCOS using two-dimensional gel electrophoresis (2DE) and mass spectrometry (MS). Methods: In the present study, we applied two-dimensional gel electrophoresis / mass spectrometry to identify proteins differentially expressed by peripheral blood CD4+ T cells in ten PCOS women compared with ten healthy women. Western blot technique was used to confirm the identified proteins. Results: Despite the overall proteome similarities, there were significant differences in the expression of seven spots between two groups (P <0.05). Three proteins, namely phosphatidylethanolamine-binding protein 1, proteasome activator complex subunit 1 and triosephosphate isomerase 1 were successfully identified by Mass technique and confirmed by western blot. All characterized proteins were over-expressed in CD4+ T cells from patients compared to CD4+ T cells from controls (P <0.05). In-silico analysis suggested that the over-expressed proteins interact with other proteins involved in cellular metabolism especially glycolysis and ferroptosis pathway. Conclusion: These findings suggest that metabolic adjustments in CD4+ T lymphocytes, which is in favor of increased glycolysis and Th2 differentiation are important in the context of PCOS.
