Abstract
This study tried to investigate the macrophage autophagy-related pyroptosis in atherosclerosis. The gene expression omnibus (GEO) dataset of GSE100927 was used for differentially expressed genes (DEG) screening, gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG), CIBERSORT, weighted correlation network analysis (WGCNA), receiver operating characteristic (ROC), gene set enrichment analysis (GSEA), and correlation analysis, and GSE159677 was used for single-cell analysis, all conducted in R software. Protein-protein interaction (PPI) was constructed in STRING and analyzed in Cytoscape. Transcription factors, drugs, and tissue co-expression network were explored in NetworkAnalyst. A total of 110 autophagy-related DEG (DEATG) were identified, and GO/KEGG revealed the top items enriched in autophagy, phagosome and lysosome. CIBERSORT showed 11 cell types were markedly differentially expressed (p < .05). WGCNA found the turquoise and yellow module were positively correlated with macrophage M0 (corr = 0.5, P = 6e-6) and M2 (corr = 0.54, P = 1e-6), respectively. Then 35 immune-related DEATG were identified, and functional analysis showed immune effector process, interleukin-6 and myeloid cell activation were enriched besides autophagy. PPI and MCC algorithm identified 6 hub genes in regulating macrophage-related autophagy, and ROC indicated high prediction value (area under curve = 0.961). GSEA enriched 6 common pathways associated with autophagy and atherosclerosis pathogenesis, and immune correlation suggested these hub genes were correlated with macrophages M0/M1, monocytes and T cells. Then venn plot found 3 central genes in mediating macrophage autophagy-associated pyroptosis in atherosclerosis, and single-cell analysis demonstrated cell distribution, then validated in THPA human samples. Our data discovered hub genes responsible for macrophage autophagy-mediated pyroptosis in atherosclerosis, and functional analysis with immune cell distribution evidenced their high phenotype-trait prediction value.

Abstract
Atherosclerosis is a chronic inflammatory vascular disease and a leading cause of death worldwide. Macrophages play an important role in inflammatory responses, cell-cell communications, plaque growth and plaque rupture in atherosclerotic lesions. Here, we review the sources, functions and complex phenotypes of macrophages in the progression of atherosclerosis, and discuss the recent approaches in modulating macrophage phenotype and autophagy for atherosclerosis treatment. We then focus on the drug delivery strategies that target macrophages or use macrophage membrane-coated particles to deliver therapeutics to the lesion sites. These biomaterial-based approaches that target, modulate or engineer macrophages have broad applications for disease therapies and tissue regeneration.

Flavonoids regulate tumor-associated macrophages - From structure-activity relationship to clinical potential (Review). Pharmacol Res 2022; 184:106419.

Abstract
In recent years, the strategy for tumor therapy has changed from focusing on the direct killing effect of different types of therapeutic agents on cancer cells to the new mainstream of multi-mode and -pathway combined interventions in the microenvironment of the developing tumor. Flavonoids, with unique tricyclic structures, have diverse and extensive immunomodulatory and anti-cancer activities in the tumor microenvironment (TME). Tumor-associated macrophages (TAMs) are the most abundant immunosuppressive cells in the TME. The regulation of macrophages to fight cancer is a promising immunotherapeutic strategy. This study covers the most comprehensive cognition of flavonoids in regulating TAMs so far. Far more than a simple list of studies, we try to dig out evidence of crosstalk at the molecular level between flavonoids and TAMs from literature, in order to discuss the most relevant chemical structure and its possible relationship with the multimodal pharmacological activity, as well as systematically build a structure-activity relationship between flavonoids and TAMs. Additionally, we point out the advantages of the macro-control of flavonoids in the TME and discuss the potential clinical implications as well as areas for future research of flavonoids in regulating TAMs. These results will provide hopeful directions for the research of antitumor drugs, while providing new ideas for the pharmaceutical industry to develop more effective forms of flavonoids.

Biomed Rep 2021; 15:95.

Abstract
Sjögren's syndrome (SS) is an autoimmune disorder that affects the salivary glands, leading to reduced secretory functions and oral and ocular dryness. The salivary glands are composed of acinar cells that are responsible for the secretion and production of secretory granules, which contain salivary components, such as amylase, mucins and immunoglobulins. This secretion process involves secretory vesicle trafficking, docking, priming and membrane fusion. A failure during any of the steps in exocytosis in the salivary glands results in the altered secretion of saliva. Soluble N-ethylmaleimide-sensitive-factor attachment protein receptors, actin, tight junctions and aquaporin 5 all serve an important role in the trafficking regulation of secretory vesicles in the secretion of saliva via exocytosis. Alterations in the expression and distribution of these selected proteins leads to salivary gland dysfunction, including SS. Several studies have demonstrated that green tea polyphenols, most notably Epigallocatechin gallate (EGCG), possess both anti-inflammatory and anti-apoptotic properties in normal human cells. Molecular, cellular and animal studies have indicated that EGCG can provide protective effects against autoimmune and inflammatory reactions in salivary glands in diseases such as SS. The aim of the present article is to provide a comprehensive and up-to-date review on the possible therapeutic interactions between EGCG and the selected molecular mechanisms associated with SS.

Ohnishi K, Yano S, Fujimoto M, Sakai M, Harumoto E, Furuichi A, Masuda M, Ohminami H, Yamanaka-Okumura H, Hara T, Taketani Y. Identification of Dietary Phytochemicals Capable of Enhancing the Autophagy Flux in HeLa and Caco-2 Human Cell Lines. Antioxidants (Basel) 2020; 9:antiox9121193. [PMID: 33261065 PMCID: PMC7760668 DOI: 10.3390/antiox9121193] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 11/20/2020] [Accepted: 11/25/2020] [Indexed: 12/24/2022] Open
Abstract
Autophagy is a major degradation system for intracellular macromolecules. Its decline with age or obesity is related to the onset and development of various intractable diseases. Although dietary phytochemicals are expected to enhance autophagy for preventive medicine, few studies have addressed their effects on the autophagy flux, which is the focus of the current study. Herein, 67 dietary phytochemicals were screened using a green fluorescent protein (GFP)-microtubule-associated protein light chain 3 (LC3)-red fluorescent protein (RFP)-LC3ΔG probe for the quantitative assessment of autophagic degradation. Among them, isorhamnetin, chrysoeriol, 2,2',4'-trihydroxychalcone, and zerumbone enhanced the autophagy flux in HeLa cells. Meanwhile, analysis of the structure-activity relationships indicated that the 3'-methoxy-4'-hydroxy group on the B-ring in the flavone skeleton and an ortho-phenolic group on the chalcone B-ring were crucial for phytochemicals activities. These active compounds were also effective in colon carcinoma Caco-2 cells, and some of them increased the expression of p62 protein, a typical substrate of autophagic proteolysis, indicating that phytochemicals impact p62 levels in autophagy-dependent and/or -independent manners. In addition, these compounds were characterized by distinct modes of action. While isorhamnetin and chrysoeriol enhanced autophagy in an mTOR signaling-dependent manner, the actions of 2,2',4'-trihydroxychalcone and zerumbone were independent of mTOR signaling. Hence, these dietary phytochemicals may prove effective as potential preventive or therapeutic strategies for lifestyle-related diseases.
