Yang et al., Lipid metabolism, viral infection, and antiviral immunity: a new host-pathogen interface, Frontiers in Cellular and Infection Microbiology, doi:10.3389/fcimb.2026.1765502
Viral infections pose significant challenges to global health. Lipid metabolism plays a crucial role in various biological processes, including cell membrane structure, signaling, and energy homeostasis. Recent studies have highlighted the intricate relationship between lipid metabolism and viral infections, revealing how viruses exploit host lipid pathways to facilitate their replication and assembly. This review aims to elucidate the mechanisms by which viruses manipulate lipid metabolism and the subsequent impact on antiviral immunity. We systematically analyze the biological basis of lipid synthesis and degradation, emphasizing the role of lipids in immune cell function and the regulation of antiviral responses. Furthermore, we explore how altered lipid metabolism can influence immune responses in disease states, providing insights into the differential utilization of lipid pathways by various viruses. This review highlights suggest potential therapeutic strategies, including the development of antiviral drugs targeting lipid metabolism, modulation of lipid pathways to enhance immune responses, and combination therapies that integrate lipid metabolism modulation with conventional antiviral treatments. Future research directions are proposed, focusing on the interaction between lipid metabolism and emerging viral strains, the application of metabolomics in viral infection studies. This comprehensive review underscores the significance of lipid metabolism as a novel host-pathogen interface, paving the way for innovative therapeutic approaches in combating viral infections.
Srivastava et al., A Brief Review on Medicinal Plants-At-Arms against COVID-19, Interdisciplinary Perspectives on Infectious Diseases, doi:10.1155/2023/7598307
COVID-19 pandemic caused by the novel SARS-CoV-2 has impacted human livelihood globally. Strenuous efforts have been employed for its control and prevention; however, with recent reports on mutated strains with much higher infectivity, transmissibility, and ability to evade immunity developed from previous SARS-CoV-2 infections, prevention alternatives must be prepared beforehand in case. We have perused over 128 recent works (found on Google Scholar, PubMed, and ScienceDirect as of February 2023) on medicinal plants and their compounds for anti-SARS-CoV-2 activity and eventually reviewed 102 of them. The clinical application and the curative effect were reported high in China and in India. Accordingly, this review highlights the unprecedented opportunities offered by medicinal plants and their compounds, candidates as the therapeutic agent, against COVID-19 by acting as viral protein inhibitors and immunomodulator in (32 clinical trials and hundreds of in silico experiments) conjecture with modern science. Moreover, the associated foreseeable challenges for their viral outbreak management were discussed in comparison to synthetic drugs.
