As the essential regulators of organ fibrosis, macrophages undergo marked phenotypic and functional changes after injury. These in macrophage phenotype function can result maladaptive repair, causing chronic inflammation development pathological fibrosis. Autophagy, a highly conserved lysosomal degradation pathway, is one major players to maintain homeostasis through clearing protein aggregates, damaged organelles, invading pathogens. Emerging evidence has shown that autophagy plays an role polarization, inflammation, Because high heterogeneity different organs, types may play roles Here, we review current understanding fibrosis highlight potential treatment Finally, important unresolved issues this field are briefly discussed. A better mechanisms contribute developing novel therapies for inflammatory diseases

Abstract Immune checkpoint molecules are promising anticancer targets, among which therapeutic antibodies targeting the PD-1/PD-L1 pathway have been widely applied to cancer treatment in clinical practice and great potential. However, this is greatly limited by its low response rates certain cancers, lack of known biomarkers, immune-related toxicity, innate acquired drug resistance, etc. Overcoming these limitations would significantly expand applications blockade improve rate survival time patients. In present review, we first illustrate biological mechanisms immune checkpoints their role healthy system as well tumor microenvironment (TME). The inhibits effect T cells TME, turn regulates expression levels PD-1 PD-L1 through multiple mechanisms. Several strategies proposed solve anti-PD-1/PD-L1 treatment, including combination therapy with other standard treatments, such chemotherapy, radiotherapy, targeted therapy, anti-angiogenic immunotherapies even diet control. Downregulation TME via pharmacological or gene regulation methods improves efficacy treatment. Surprisingly, recent preclinical studies shown that upregulation also blockade. Immunotherapy a strategy provides novel insight into applications. This review aims guide development more effective less toxic immunotherapies.

Cytotoxic T cells are important effectors of anti-tumor immunity. While tumor killing is ascribed to CD8+ cell function, pre-clinical and clinical studies have identified intra-tumoral CD4+ that possess cytotoxic programs can directly kill cancer cells. found in other disease settings including infection autoimmunity. Here, we review the phenotypic functional characteristics non-cancer contexts. We conduct a comparative examination cytolytic mechanisms across states synthesize features define these independent context. discuss regulatory driving ontogeny effector function evidence for relevance cancer. In this context, highlight gaps understanding biology as well potential use immunotherapies specific cancers.

Abstract Spatial transcriptomics technologies generate gene expression profiles with spatial context, requiring spatially informed analysis tools for three key tasks, clustering, multisample integration, and cell-type deconvolution. We present GraphST, a graph self-supervised contrastive learning method that fully exploits data to outperform existing methods. It combines neural networks learn informative discriminative spot representations by minimizing the embedding distance between adjacent spots vice versa. demonstrated GraphST on multiple tissue types technology platforms. achieved 10% higher clustering accuracy better delineated fine-grained structures in brain embryo tissues. is also only can jointly analyze slices vertical or horizontal integration while correcting batch effects. Lastly, superior deconvolution capture niches like lymph node germinal centers exhausted tumor infiltrating T cells breast tissue.

Single-cell technologies, particularly single-cell RNA sequencing (scRNA-seq) methods, together with associated computational tools and the growing availability of public data resources, are transforming drug discovery development. New opportunities emerging in target identification owing to improved disease understanding through cell subtyping, highly multiplexed functional genomics screens incorporating scRNA-seq enhancing credentialling prioritization. ScRNA-seq is also aiding selection relevant preclinical models providing new insights into mechanisms action.
