Control of a viral infection in vivo requires a rapid and efficient cytotoxic-T-lymphocyte response. We demonstrate that lentivirus-mediated introduction of antigen in dendritic cells confers a protective antiviral immunity in vivo in a lymphocytic choriomeningitis virus model. Therefore, lentiviral vectors may be excellent vaccine candidates for viral infections.

Background: The progression of bladder cancer (BC) from non-muscle-invasive bladder cancer (NMIBC) to muscle-invasive bladder cancer (MIBC) significantly increases disease severity. Although the tumor microenvironment (TME) plays a pivotal role in this process, the heterogeneity of tumor cells and TME components remains underexplored.
Methods: We characterized the transcriptomes of single cells from 11 BC samples, including 4 NMIBC, 4 MIBC, and 3 adjacent normal tissues.

Objective: This study aims to investigate the correlation between the development of diabetic retinopathy (DR) and the changes in corneal sub-basal nerve plexus (SNP) and corneal dendritic cells (DCs).
Methods: 58 patients with type 2 diabetes mellitus (T2DM) and 30 age- and sex-matched healthy participants underwent assessment of the corneal nerve. The DR group was divided into no diabetic retinopathy (NDR) and 29 eyes with mild to moderate non-proliferative diabetic retinopathy (NPDR).
Background: Orthokeratology (OK) contact lenses are increasingly prescribed for myopia control but their impact on corneal epithelial immune cells (CEIC) is unclear. This study compares CEIC in OK wearers to soft contact lens (SCL) wearers and non-wearers.
Methods: In vivo confocal microscope images at the corneal central and mid-peripheral subbasal level were evaluated in 18 OK wearers, 18 SCL wearers and 18 non-wearers (mean age 27.

Chronic allograft rejection is mainly mediated by indirect recognition. Dendritic cells (DCs), as the major antigen-presenting cells in indirect recognition, exhibit an enhanced antigen-presenting ability in chronic rejection, but the specific mechanism is still unclear. Here, we found that pretreatment with high mobility group box-1 protein (HMGB1) in vivo can induce trained immunity in DCs.

Background: Varicose veins (VVs) are a common chronic venous disorder with a complex pathophysiology involving immune dysregulation, inflammation, and genetic predisposition. This study aims to identify immune-related causal factors in the pathogenesis of VVs using Mendelian randomization (MR).
Methods: A two-sample MR analysis was conducted to assess the causal relationships between immune cell phenotypes and VVs.
