Purpose: To describe the patterns of ocular inflammation following COVID-19 vaccination, assess underlying commonalities and understand outcomes.

Methods: Retrospective, multicenter cohort study, conducted between 2020 and 2021. Patients with no previous uveitis history (de novo) or a known uveitis history (recurrent) who developed ocular inflammation within 42 days of COVID-19 vaccination were identified.

Objectives: GCA is a granulomatous vasculitis affecting large vessels, leading to intimal occlusion accompanied by the accumulation of myofibroblasts. Histopathologically, GCA is characterized by destruction of the tunica media and hypertrophy of the intima with invasion of activated CD4+ T cells, macrophages and multinucleated giant cells (MNGCs). Despite these well-defined histopathological features, the molecular pathology of GCA has largely remained elusive.

Antigen presentation plays a critical role in the pathogenesis of immune-mediated disorders. This study aimed to investigate the effects of IFN-γ and a cytokine mix (5MIX: IL-1α, IL-17A, IL-22, OsM, and TNF-α) on the antigen-presenting capabilities of keratinocytes, with a specific focus on immune-mediated dermatological conditions such as psoriasis (Ps). To achieve this, keratinocytes were treated with IFN-γ and 5MIX, and their impact on the expression of key antigen-presentation molecules, HLA-DRα and CD74, was assessed.

Background: It has been demonstrated that COVID-19 vaccines confer significant protection, but temporal decay in the vaccine-induced antibodies has been reported; therefore, a third booster dose was considered. Human leukocyte antigen (HLA) class II molecules act as antigen presenting structures, play critical roles in the formation of an efficient antibody response. The current study aimed to evaluate the anti-receptor binding domain (RBD) antibody response after the booster dose of SpikoGen® vaccine in individuals with a history of Sinopharm primary vaccination series and its association with HLA-DQB1 and -DRB alleles.

Purpose: To investigate the follicle microenvironments of women with premature ovarian insufficiency (POI), with normal ovarian reserve function, and who are older (age >40 years) and to identify potential therapeutic targets.

Patients And Methods: In total, 9 women who underwent in vitro fertilization(IVF) or intracytoplasmic sperm injection(ICSI) were included in this study. The first punctured follicle of each patient was used.
