Toll-like receptor 7 (TLR7) is a member of the toll-like receptor (TLR) family that is essential in the innate immune system. In this study, we established a heterozygous TLR7 knockout H9 cell line using CRISPR/Cas9. TLR7 knockout H9 cells maintained their pluripotency and exhibited the ability to differentiate into the three germ layers without any karyotype abnormalities.

Ischemic stroke (IS) has high morbidity/mortality with limited treatments. This study screened core copper homeostasis-related genes in IS and validated their function as precise intervention targets. Human IS gene chip data were retrieved from GEO, and copper homeostasis genes from multiple databases.

Objective: This research aimed at evaluating the effectiveness and safety of nitazoxanide and escitalopram as adjuvant therapies in patients with rheumatoid arthritis (RA).
Methods: In this randomized controlled parallel study, 90 patients with active RA were randomized into three groups; group 1 (control group; n = 30) which received traditional therapy, group 2 (Nitazoxanide group; n = 30) which received traditional therapy plus 1 gm/day oral nitazoxanide, and group 3 (Escitalopram group; n = 30) which received traditional therapy plus 10 mg/day oral escitalopram for three months. At baseline and 3 months after treatment, clinical and functional assessments were done through the 28-joint count disease activity score using C-reactive protein (DAS28-CRP), the health assessment questionnaire-disability index (HAQ-DI), and the patient's global assessment (PGA).

The immune system uses a variety of DNA sensors, including endo-lysosomal Toll-like receptors 9 (TLR9) and cytosolic DNA sensor cyclic GMP-AMP (cGAMP) synthase (cGAS). These sensors activate immune responses by inducing the production of a variety of cytokines, including type I interferons (IFN). Activation of cGAS requires DNA-cGAS interaction.

Achieving immune tolerance is a key goal in organ transplantation, as it eliminates the need for long-term immunosuppression. Regulatory B cells (Bregs) present a promising strategy for inducing tolerance. Our previous findings demonstrate that the adoptive transfer of ex vivo-expanded murine splenic B regulatory cells, referred to as TLR-Bregs (TLR9/TLR4 stimulation), induces tolerance to allografts.

20(R)-ginsenoside Rg3 can reduce the effects of oxidative stress and cell death in cerebral ischemia‒reperfusion injury (CIRI). Neuroinflammation is crucial post-CIRI, but how 20(R)-Rg3 affects ischemia‒reperfusion-induced neuroinflammation is unclear. To study 20(R)-Rg3's effects on neuroinflammation and neuronal preservation in stroke models and explore toll-like receptor 4/myeloid differentiation factor-88/nuclear factor kappa B (TLR4/MyD88/NF-κB) pathway mechanisms.
