Article Abstract
Aim: To explore the immune cell infiltration and molecular mechanisms of retinal ischemia-reperfusion injury (RIRI) to identify potential therapeutic targets.
Methods: In the bulk RNA-seq analysis, This study performed differential gene expression analysis, weighted gene co-expression network analysis, and protein-protein interaction network analysis to identify hub genes. QuanTIseq was used to determine the composition of infiltrating immune cells. Following the identification of hub genes, single-cell RNA-seq analysis was employed to pinpoint the specific immune cell types expressing these hub genes. Cell-cell communication analysis to explore signaling pathways and interactions between immune cells was further performed. Finally, the expression of these key immune regulators using quantitative real-time polymerase chain reaction (qRT-PCR) was validated.
Results: Bulk RNA-seq analysis identified , , , , 9, , , and as hub genes, with strong correlations to immune cell infiltration. Single-cell RNA-seq analysis further revealed six immune cell clusters, showing predominantly in microglia and in dendritic cells (DCs). And cell-cell communication analysis showed that microglia and DCs play central roles in coordinating immune activity. qRT-PCR validated the upregulation of these genes.
Conclusion: In the acute phase of RIRI, and may be the potential therapeutic targets to reduce inflammation and promote neurological function recovery.

Clonal Hematopoiesis in Nonmalignant Disease: Functional Consequences of Mutated Immune Cells by Clonal Hematopoiesis in the Diseased Tissue.

Clonal hematopoiesis, originally identified as a precursor to hematologic malignancies, has emerged as a significant factor in various nonmalignant diseases. Recent research highlights how somatic mutations in hematopoietic stem cells lead to the expansion of circulating mutated immune cells that exert profound effects on organ function and disease progression. These mutated clones display altered inflammatory profiles and tissue-specific functional consequences, contributing to various diseases including atherosclerotic cardiovascular disease, osteoporosis, heart failure, and neurodegenerative conditions.

Background: Parasite antigens and plasma lipopolysaccharide (LPS) levels from luminal origin in visceral leishmaniasis (VL) patients are correlated with cellular activation and low CD4+T cell counts.
Objectives: Our aim was to verify whether Leishmania infantum infection damages the intestinal barrier and whether combination antimonial/antibiotic contributes to the reduction of LPS levels and immune activation.
Methods: Golden hamsters were grouped in: G1-uninfected; G2-infected with L.

Tumor necrosis factor-alpha (TNF-α) is a cytokine involved in the immune-inflammatory response. It can induce an odontoblastic phenotype and enhance biomineralization in dental pulp mesenchymal stem cells but does not have the same effect on osteoblasts. The reasons for this differential response, despite the shared lineage of these cell types, are not yet clear.

Ion channels are integral membrane proteins which facilitate rapid transport of small ions into and out of the cell and between organelles and cytosol. Cytolytic lymphocytes including natural killer (NK) cells principally kill virus-infected and cancer cells by releasing cytolytic granules within the immunological synapse, formed between target and effector cells. This process strongly depends on Ca2+ signaling, which in human NK cells is controlled by the phospholipase C (PLCγ)/inositol-1,4,5-triphospate receptor (IP3R)/calcium release-activated calcium channel (CRAC) axis.
