circRACGAP1 Promotes Non-Small Cell Lung Cancer Proliferation by Regulating miR-144-5p/CDKL1 Signaling Pathway

Expression patterns of circRACGAP1 and miR-144-5p in non-small cell lung cancer tissues and cell lines were quantified by qRT-PCR analysis. Then, the function of circRACGAP1 on cell proliferation and tumorigenesis were confirmed in vitro and in vivo using CCK-8 assay, colony formation, EdU incorporation, and xenograft technique.

DRP1 Promotes Lactate Utilization in KRAS‐Mutant Non‐Small Cell Lung Cancer Cells

Scientists developed a lactate‐dependent cell proliferation assay and found that dynamin‐related protein (DRP1), which was highly expressed in KRAS‐mutant non‐small cell lung cancer (NSCLC), was required for tumor cells to proliferate and uses lactate as fuel, demonstrating the critical role of DRP1 in the metabolic reprogramming of NSCLC.

Complement and Tissue Factor-Enriched Neutrophil Extracellular Traps Are Key Drivers in COVID-19 Immunothrombosis

The authors investigated how complement interacted with the platelet/neutrophil extracellular traps (NETS)/thrombin axis, using COVID-19 specimens, cell-based inhibition studies and NETs/human aortic endothelial cell co-cultures.

Inhibition of Mitophagy Drives Macrophage Activation and Anti-bacterial Defense during Sepsis

Scientists showed that lipopolysaccharide in combination with IFNγ, inhibited PINK1-dependent mitophagy in macrophages through a STAT1-dependent activation of the inflammatory caspases 1 and 11.

Immune-Mobilizing Monoclonal T Cell Receptors Mediate Specific and Rapid Elimination of Hepatitis B-Infected Cells

The ability of immune mobilizing monoclonal T cell receptors Against Virus-envelope to activate and redirect polyclonal T cells towards cells containing integrated HBV and cells infected with hepatitis B virus was assessed using cytokine secretion assays and imaging‐based killing assays.

Neutrophil Extracellular Traps Amplify Neutrophil Recruitment and Inflammation in Neutrophilic Asthma by Stimulating the Airway Epithelial Cells to Activate the TLR4/NF-κB Pathway and Secrete Chemokines

Formation of neutrophil extracellular traps (NETs) and neutrophil swarming was seen in a mouse model of neutrophilic asthma. Additionally, NETs were found to stimulate airway cells to express CXCL1, CXCL2, and CXCL8 via the TLR4/NF-κB pathway, which recruits neutrophils to the inflammation site.
