Toll-Like Receptor 7 (TLR7) is recognized for its role in immune responses, particularly in detecting viral RNA. However, emerging evidence suggests that TLR7 may also contribute to ocular development. In this study, we assessed the expression pattern of TLR7 in various CD-1 mouse eye compartments during critical developmental stages, from embryonic day 12 to 16, as well as in adult tissues such as the cornea, pigmented epithelium, neural retina and lens. Our findings reveal a region-specific and time-dependent expression of TLR7, suggesting that it may play a role in the morphogenetic processes that shape the eye during intrauterine development.

Purpose: A disintegrin-like and metalloprotease with thrombospondin type 1 motif 13 (ADAMTS13) has been found to increase and to be associated with diabetic retinopathy (DR). The study aimed to identify the role of ADAMTS13 in the pathogenesis of angiogenesis in DR.
Methods: ADAMTS13 expression was evaluated in human retinal microvascular endothelial cells (HRMVECs), vitreous sample from patients with proliferative DR and diabetic mice model using western blot, real time-quantitative PCR, immunofluorescence and ELISA.

Crohn's disease (CD) is a chronic inflammatory bowel condition that significantly impairs patients' quality of life. With no cure currently available, the need to discover novel biomarkers and develop effective therapeutic strategies is paramount. This study used a comprehensive machine learning approach to identify key predictive genes for CD, including S100A8, IGFBP5, CTSK, and S100P.

Acute sleep deprivation (SD) rapidly alleviates depression, addressing a critical gap in mood disorder treatment. Rapid eye movement SD (REM SD) modulates the excitability of vasoactive intestinal peptide (VIP) neurons, influencing the synaptic plasticity of pyramidal neurons. However, the precise mechanism remains undefined.

Purpose: To explore the causal links between antihypertension drugs usage and age-related macular degeneration (AMD).
Methods: Multiple genetic analyses, including summary data-based Mendelian randomization (SMR), traditional MR, and colocalization analysis, were used to explore the causal associations between antihypertension drugs and AMD. Clinical data from the UK Biobank and the National Health and Nutrition Examination Survey (NHANES) was applied to refined risk assessment of specific antihypertensive medications in the context of AMD development.

Traditional live attenuated vaccines (LAVs) are typically developed through serial passaging or genetic engineering to introduce specific mutations or deletions. While viral RNA secondary or tertiary structures have been well-documented for their multiple functions, including binding with specific host proteins, their potential for LAV design remains largely unexplored. Herein, using Zika virus (ZIKV) as a model, we demonstrate that targeted disruption of the primary sequence or tertiary structure of a specific viral RNA element responsible for Musashi-1 (MSI1) binding leads to a tissue-specific attenuation phenotype in multiple animal models.
