- It is well established that the function of DCs (dendritic cells) is impaired during malaria infection; however, the underlying mechanisms responsible for this impairment remain poorly understood. In this study, we found that ATG5 (autophagy related 5) deficiency in DCs significantly suppressed the growth of malaria blood-stage parasites, and this effect was independent of both canonical and non-canonical macroautophagy/autophagy pathways in these cells. The reduced parasite growth observed in mice was associated with an enhanced parasite-specific CD4 T cell response, which provided crucial support for the functional activation of Plasmodium-specific CD8 T cells. Mechanistically, ATG5 deficiency led to a marked increase in the expression of the phagocytic receptor CD209A/DC-SIGN on conventional DCs (cDCs), thereby enhancing their capacity to activate Plasmodium-specific CD4 T cell responses. Furthermore, the expression of CD209A was mediated by the TLR2 (toll-like receptor 2) signaling pathway, which was significantly augmented in the absence of ATG5. Thus, we reveal a novel role for ATG5 in modulating anti-malarial cellular immune responses by influencing TLR2-mediated CD209A expression in cDCs. These findings not only enhance our understanding of impaired DC function during malaria infection but also provide valuable insights for the design of more effective malaria vaccines.

Fan YonglingJiao ShimingLi HangyuGao YuanliFang JiaqinZhang KunGuo ShuaiXu WenyueLiu Taiping - TM4SF1, a small transmembrane glycoprotein, has been implicated in tumor progression across multiple cancers. However, its functional and regulatory roles in esophageal cancer, particularly esophageal squamous cell carcinoma (ESCC), remain unclear. This study aims to characterize TM4SF1 expression in an ESCC cell line, KYSE150, determine its biological role in tumor cell phenotypes, and profile miRNA changes after knockdown and perform in silico target or pathway analyses. First, gene expression was analyzed in the KYSE150 cell line by qRT-PCR. shRNA-mediated knockdown was applied to the KYSE150 cells, followed by proliferation, migration, and apoptosis assays. MiRNA sequencing followed by bioinformatic analyses predicted microRNAs and potential genes targeting TM4SF1, which also included putative composite pathways and gene ontologies. gene expression was significantly upregulated in the KYSE150 cells compared to EC109 ESCC and HET1A cells, a normal esophageal epithelial cell. Functional bioassays revealed that knockdown significantly reduced cell proliferation (MTT and CCK-8 assays) by 46%, while reducing wound closure at 24 h by 30.5% with recovery by 48 h and increased 90% of caspase 3/7 activity. The exploratory sequencing of miRNAs revealed the ten most differentially expressed miRNAs (hsa-miR-6510-3p, hsa-miR-675-5p, hsa-miR-524-5p, hsa-miR-9902, hsa-miR-520f-3p, hsa-miR-3192-5p, hsa-miR-1973, hsa-miR-3614-5p, hsa-miR-501-3p, and hsa-miR-1298-5p), whereas bioinformatic analyses predicted 54 target gene predictions, including TP53, RB1, and ICAM3, and 13 composite pathways that encompassed processes such as apoptosis, cell adhesion, and metabolic regulation. This study provides preliminary and useful insights into the role of TM4SF1 within the KYSE150 ESCC cell-line model and provide a basis for future validation in additional ESCC models, alongside initial investigations into its molecular mechanisms, and underscores the necessity of further validation in diverse cells and models and possible therapeutic implications. - Source: PubMed

Stephen AnnatashaWu Yuan SengRahim Nur SyafiqahTune Bernadette Xin JieLee Michelle FeliciaKhan AbbasSim Maw ShinHashim Najihah MohdVelaga Appalaraju - Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by dysregulated immune responses and impaired epidermal barrier function. A major therapeutic challenge is the identification of molecular targets capable of coordinately regulating both processes. Here, we identify dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) on keratinocytes as one such target. We demonstrate functional expression of DC-SIGN on keratinocytes and show that its engagement by a synthetic heparin analogue-exemplified by the oligosaccharide octaparin-produces profound therapeutic benefits. In a DNCB-induced murine model of AD, topical application of octaparin alleviated disease severity, suppressed both Th1- and Th2-type inflammatory responses, and restored expression of key epidermal barrier proteins such as filaggrin and loricrin. Metabolomic profiling further confirmed that octaparin treatment globally reversed disease-associated metabolic perturbations. Mechanistically, engagement of DC-SIGN on keratinocytes attenuated JAK-STAT signalling induced by key AD-associated cytokines, including IFN-γ and IL-4/IL-13. This attenuation led to reduced production of pro-inflammatory chemokines and cytokines, accompanied by increased expression of barrier-related genes. Critically, inhibition of DC-SIGN abolished the therapeutic effects of octaparin, establishing a causal requirement for this receptor. Our findings unveil a previously unrecognized role for keratinocyte DC-SIGN in coordinating immune and barrier responses and highlight it as a druggable target for novel therapeutic strategies in AD. - Source: PubMed

McLouth Christopher JHazelwood Hunter SFrank Jacqueline AHarp Jordan PDornbos DavidFraser Justin FPennypacker Keith R - In vivo-generated monocyte-derived dendritic cells (moDCs) play a pivotal role in inducing effective immune responses against infections and cancer due to their exceptional cross-presentation capabilities. However, the in vivo generation of moDCs during immunotherapy is constrained by the absence of safe and efficient in vivo strategies. Here, we propose a chitosan oligosaccharide-based CaCO nanoparticle-loaded hydrogel (CCH) to facilitate effective in vivo monocyte-to-moDC conversion by leveraging its in-situ spatiotemporal regulation capabilities. The CCH promotes the secretion of chemokines to recruit monocytes and then targets a dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN)-pathway to facilitate the differentiation of monocytes into moDCs within a subcutaneous immune niche formed by CCH. After the removal of DC-SIGN cells in DC-SIGN-DTR mice, the proportion of CCH-induced moDCs significantly decreased, indicating the DC-SIGN-dependent conversion of moDCs. Accordingly, the tumor cell loaded-CCH (TCH)-induced moDCs facilitate cross-presentation to prime T cells and enhance robust antitumor T cell memory responses. Thus, subcutaneous injection of TCH effectively prevent the growth of primary liver cancer and patient-derived xenograft (PDX) colorectal cancer. Moreover, TCH inhibits postoperative tumor recurrence, providing promising advancements in immunotherapy. Our CCH-based strategy provided important insights on how to in vivo induce moDCs to harness cross-presentation for anti-tumor therapy. - Source: PubMed
