Aim: This study was conducted to evaluate the in vitro effects of hydroxychloroquine (HCQ) on histone deacetylase (HDAC) enzyme activity and interleukin (IL)-6, IL-10, and tumor necrosis factor-alpha (TNF-α) expression. HDAC enzyme activity and the expression of inflammation markers were tested, with the presence of the HDAC inhibitor valproic acid, in human primary cell cultures prepared from two different tissues.
Material And Methods: Primary cell cultures were prepared.

Bacterial infections, particularly those caused by drug-resistant bacteria, represent a pressing global health challenge. During the interaction between pathogen infection and host defense, bacterial infections initiate the host's immune response, which involves the activation of proteases that play a critical role in antibacterial defense. Granzyme B (GzmB), a key immune-related biomarker associated with cytotoxic T lymphocytes (CTLs), plays a pivotal role in this process.

An increasing number of patients utilizing in vitro fertilization (IVF) and assisted reproductive technology (ART) are characterized as impaired or poor ovarian responders (PORs). Owing to its unclear molecular etiology, the management of patients with age-related ovarian characteristics remains a controversial and complex clinical concern. Therefore, it is important to identify and understand the etiological causes behind POR to develop more effective and efficient management strategies for these patients.

Leaky and structurally abnormal blood vessels and increased pressure in the tumor interstitium reduce the infiltration of CAR-T cells in solid tumors, including triple-negative breast cancer (TNBC). Furthermore, high burden of tumor cells may cause reduction of infiltrating CAR-T cells and their functional exhaustion. In this study, various effector-to-target (E:T) ratio experiments are established to model the treatment using CAR-T cells in leukemia (high E:T ratio) and solid tumor (low E:T ratio).

Osteoarthritis (OA) is a globally prevalent degenerative joint disease. Recent studies highlight the role of ferroptosis in OA progression. Targeting ferroptosis regulation presents a promising therapeutic strategy for OA; however, current research primarily focuses on single targets associated with ferroptosis.
