Abstract
The functions of macrophages are governed by distinct polarization phenotypes, which can be categorized as either anti-tumor/M1 type or pro-tumor/M2 type. Glycosylation is known to play a crucial role in various cellular processes, but its influence on macrophage polarization is not well-studied. In this study, we observed a significant decrease in bisecting GlcNAc during M0-M1 polarization, and impaired bisecting GlcNAc was found to drive M0-M1 polarization. Using a glycoproteomics strategy, we identified Lgals3bp as a specific glycoprotein carrying bisecting GlcNAc. A high level of bisecting GlcNAc modification facilitated the degradation of Lgals3bp, while a low level of bisecting GlcNAc stabilized Lgals3bp. Elevated levels of Lgals3bp promoted M1 polarization through the activation of the NF-кB pathway. Conversely, the activated NF-кB pathway significantly repressed the transcription of MGAT3, leading to reduced levels of bisecting GlcNAc modification on Lgals3bp. Overall, our study highlights the impact of glycosylation on macrophage polarization and suggests the potential of engineered macrophages via glycosylated modification. Video Abstract.

Single-Dose Treatment With Vesicular Stomatitis Virus-Based Ebola Virus Vaccine Expressing Ebola Virus-Specific Artificial Micro-RNA Does Not Protect Mice From Lethal Disease. J Infect Dis 2023; 228:S677-S681. [PMID: 37186162 PMCID: PMC10651205 DOI: 10.1093/infdis/jiad121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 04/13/2023] [Accepted: 04/25/2023] [Indexed: 05/17/2023] Open
Abstract
Although significant progress has been made in the development of therapeutics against Ebola virus (EBOV), we sought to expand upon existing strategies and combine an RNA interference-based intervention with the approved vesicular stomatitis virus-based Ebola virus (VSV-EBOV) vaccine to conjointly treat and vaccinate patients during an outbreak. We constructed VSV-EBOV vectors expressing artificial micro-RNAs (amiRNAs) targeting sequences of EBOV proteins. In vitro experiments demonstrated a robust decrease in EBOV replication using a minigenome system and infectious virus. For in vivo evaluation, mouse-adapted EBOV-infected CD-1 mice were treated 24 hours after infection with a single dose of the VSV-EBOV amiRNA constructs. We observed no difference in disease progression or survival compared to the control-treated mice. In summary, while amiRNAs decrease viral replication in vitro, the effect is not sufficient to protect mice from lethal disease, and this therapeutic approach requires further optimization.

The miR-23-27-24 clusters drive lipid-associated macrophage proliferation in obese adipose tissue. Cell Rep 2023; 42:112928. [PMID: 37542720 PMCID: PMC10712211 DOI: 10.1016/j.celrep.2023.112928] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 06/19/2023] [Accepted: 07/17/2023] [Indexed: 08/07/2023] Open
Abstract
Identifying molecular circuits that control adipose tissue macrophage (ATM) function is necessary to understand how ATMs contribute to tissue homeostasis and obesity-induced insulin resistance. In this study, we find that mice with a myeloid-specific knockout of the miR-23-27-24 clusters of microRNAs (miRNAs) gain less weight on a high-fat diet but exhibit worsened glucose and insulin tolerance. Analysis of ATMs from these mice shows selectively reduced numbers and proliferation of a recently reported subset of lipid-associated CD9+Trem2+ ATMs (lipid-associated macrophages [LAMs]). Leveraging the role of miRNAs to control networks of genes, we use RNA sequencing (RNA-seq), functional screens, and biochemical assays to identify candidate target transcripts that regulate proliferation-associated signaling. We determine that miR-23 directly targets the mRNA of Eif4ebp2, a gene that restricts protein synthesis and proliferation in macrophages. Altogether, our study demonstrates that control of proliferation of a protective subset of LAMs by noncoding RNAs contributes to protection against diet-induced obesity metabolic dysfunction.
