NKG2D chimeric antigen receptor (CAR)-modified T cells (NKG2D CAR-T cells) have been reported to be preclinically efficient in several tumors, but little is known whether NKG2D CAR-T cells co-expressing IL21 (IL21-NKG2D CAR-T cells) display greater antitumor activity in multiple myeloma (MM). In this study, the lentivirus has been produced for expression of the IL21 sequence linked to the extracellular NKG2D sequence with the signal peptide linked through the CD8α hinge-transmembrane domain to the 4-1BB molecule fused with the CD3-ζ chain signaling domain, and the engineered IL21-NKG2D CAR-T cells and NKG2D CAR-T cells were constructed. The CAR expression on CAR-T cells was assessed by flow cytometry, and the killing effects of CAR-T cells on MM were assessed by the cytotoxicity assay and ELISA assay.

Article Synopsis
  • The study reveals the crystal structure of a hammerhead ribozyme containing a pseudoknot, showing it closely resembles the pistol ribozyme in secondary structure.
  • The ribozyme's activity relies more on the presence of the G8 2'OH than on magnesium ions, suggesting similar catalytic mechanisms to the extended hammerhead but not to the pistol ribozyme.
  • The findings highlight that although the overall structure is alike, the cleavage site differs, allowing the PK hammerhead to maintain its unique mechanism and exhibit better activity compared to other hammerhead ribozymes.

The mitogen-activated protein kinase kinase 4 (MKK4), a member of the MAP kinase kinase family, directly phosphorylates and activates the c-Jun NH2-terminal kinases (JNK), in response to proinflammatory cytokines and cellular stresses. Regulation of the MKK4 activity is considered to be a novel approach for the prevention and treatment of inflammation. The aim of this study was to identify whether fisetin, a potential anti-inflammatory compound, targets MKK4-JNK cascade to inhibit lipopolysaccharide (LPS)-stimulated inflammatory response.

The unfolded protein response (UPR) relieves endoplasmic reticulum (ER) stress through multiple strategies, including reducing protein synthesis, increasing protein folding capabilities, and enhancing misfolded protein degradation. After a multi-omics analysis, we find that signal recognition particle 14 (SRP14), an essential component of the SRP, is markedly reduced in cells undergoing ER stress. Further experiments indicate that SRP14 reduction requires PRKR-like ER kinase (PERK)-mediated eukaryotic translation initiation factor 2α (eIF2α) phosphorylation but is independent of ATF4 or ATF3 transcription factors.

Biominerals, the inorganic minerals of organisms, are known mainly for their physical property-related functions in modern living organisms. Our recent discovery of the enzyme-like activities of nanomaterials, coined as nanozyme, inspires the hypothesis that nano-biominerals might function as enzyme-like catalyzers in cells. Here we report that the iron cores of biogenic ferritins act as natural nanozymes to scavenge superoxide radicals.

In the effort to identify deubiquitinating enzymes required for the growth of colorectal cancer (CRC) cells, we found that OTUB2 knockdown markedly inhibited the viability of these cancer cells in culture and in xenografted mice. It was also found that the level of OTUB2 was elevated in primary CRCs, and its high expression was a poor prognostic indicator for the patients. Interestingly, immunoprecipitation and LC-MS/MS analyses suggested that β-Catenin was an OTUB2-interacting protein, and there was a positive correlation between OTUB2 and β-Catenin expression in both CRC tissues and cell lines.

The extensive research into developing novel strategies for detecting respiratory syndrome coronavirus 2 (SARS-CoV-2) antigens in clinical specimens, especially the sensitive point-of-care testing method, is still urgently needed to reach rapid screening of viral infections. Herein, a new lateral flow immunoassay (LFIA) platform was reported for the detection of SARS-CoV-2 spike-S1 protein antigens, in which four sensitive and specific SARS-CoV-2 mouse monoclonal antibodies (MmAbs) were tailored by using quantum dot (QD)-loaded dendritic mesoporous silica nanoparticles modified further for achieving the -COOH group surface coating (named Q/S-COOH nanospheres). Importantly, compact QD adsorption was achieved in mesoporous channels of silica nanoparticles on account of highly accessible central-radial pores and electrostatic interactions, leading to significant signal amplification.
