Coronavirus disease-19 (COVID-19) can be a fatal disease and is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). SARS-CoV2 is an enveloped virus that belongs to the Beta coronavirus subfamily. After entering into the target cells, this virus replicates rapidly and leads to cellular damage and uncontrolled pulmonary inflammation. Huge amounts of inflammatory cytokines and chemokines are produced by infected lung cells and are associated with monocyte recruitment and accumulation of inflammatory macrophages at the site of infection. Mitochondrial citrate carrier (CIC) expression increases in these macrophages, which results in elevated levels of cytosolic citrate and the production of inflammatory mediators. In this perspective article, we discuss the role of mitochondrial CIC in the metabolism of inflammatory macrophages and we propose that inhibition of this carrier might be a novel therapeutic approach for COVID-19 patients.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the result of an exaggerated inflammatory response triggered by a variety of pulmonary and systemic insults. The lung tissues are comprised of a variety of cell types, including alveolar epithelial cells, pulmonary vascular endothelial cells, macrophages, neutrophils, and others. There is mounting evidence that these diverse cell populations within the lung interact to regulate lung inflammation in response to both direct and indirect stimuli.

Emerging techniques of additive manufacturing, such as vat-based three-dimensional (3D) bioprinting, offer novel routes to prepare personalized scaffolds of complex geometries. However, there is a need to develop bioinks suitable for clinical translation. This study explored the potential of bacterial-sourced methacrylate levan (LeMA) as a bioink for the digital light processing (DLP) 3D bioprinting of bone tissue scaffolds.

Natural plant-derived polysaccharides exhibit substantial potential for treating ulcerative colitis (UC) owing to their anti-inflammatory and antioxidant properties and favorable safety profiles. However, their practical application faces several challenges, including structural instability in gastric acid, imprecise targeting of inflamed regions, and limited intestinal retention times. To address these limitations, pH-responsive, colon-targeting microspheres (pWGPAC MSs) are developed for delivering phosphorylated wild ginseng polysaccharides (pWGP) to alleviate UC.

Wear particle reaction is present in every arthroplasty. Sometimes, this reaction may lead to formation of large pseudotumors. As illustrated in this case, the volume of the reaction may be out of proportion to the volume of the wear scar.

Hepatocellular carcinoma (HCC) is a major global health issue characterized by poor prognosis and complex tumor biology. One of the critical components of the HCC tumor microenvironment (TME) is tumor-associated macrophages (TAMs), which play a pivotal role in modulating tumor growth, immune evasion, and metastasis. Macrophages are divided into two major subtypes: pro-inflammatory M1 and anti-inflammatory M2, both of which may exist in TME with altered function and proportion.
