Article Abstract

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causative agent of coronavirus disease 2019. Few studies have compared replication dynamics and host responses to SARS-CoV-2 in cell lines from different tissues and species. Therefore, we investigated the role of tissue type and antiviral genes during SARS-CoV-2 infection in nonhuman primate (kidney) and human (liver, respiratory epithelial, gastric) cell lines. We report different viral growth kinetics and release among the cell lines despite comparable ACE2 expression. Transcriptomics revealed that absence of in nonhuman primate cells appeared to enhance inflammatory responses without effecting infectious viral titer. Deletion of in respiratory epithelial cells increased viral replication. Impaired infectious virus release was detected in Huh7 but not Huh7.5 cells, suggesting a role for . Gastric cells MKN45 exhibited robust antiviral gene expression and supported viral replication. Data here provide insight into molecular pathogenesis of and alternative cell lines for studying SARS-CoV-2 infection.

IGLV3-21-directed bispecific antibodies activate T cells and promote killing in a high-risk subset of chronic lymphocytic leukemia.

We previously used a disease-specific B cell receptor (BCR) point mutation (IGLV3-21R110) for selective targeting of a high-risk subset of chronic lymphocytic leukemia (CLL) with chimeric antigen receptor (CAR) T cells. Since CLL is a disease of the elderly and a significant fraction of patients is not able to physically tolerate CAR T cell treatment, we explored bispecific antibodies as an alternative for precision targeting of this tumor mutation. Heterodimeric IgG1-based antibodies consisting of a fragment crystallizable region (Fc) attached to both an anti-IGLV3-21R110 Fab and an anti-CD3 (UCHT1) single chain variable fragment (R110-bsAb) selectively killed cell lines engineered to express high levels of the neoepitope as well as primary CLL cells using healthy donor and CLL patient-derived T cells as effectors.

Activated B-cell diffuse large B-cell lymphoma (ABC-DLBCL) is an aggressive cancer with poor response to standard chemotherapy. In search of new therapeutic leads, a library of 435 fractions prepared from the Irish marine biorepository was screened against 2 ABC-DLBCL cell lines (TMD8 and OCI-Ly10) and a non-cancerous control cell line (CB33). Active fractions are prioritized based on potency and selectivity.

The Transcription Factor MYB8 Positively Regulates Flavonoid Biosynthesis of Scutellaria baicalensis in Response to Drought Stress.

Drought stress dynamically reprograms specialised metabolism in medicinal plants. However, the transcriptional regulatory modules governing stress-adaptive metabolite synthesis remain poorly characterised. Here, we identified SbMYB8 as a drought-responsive transcription factor showing nuclear localisation and dose-dependent induction under drought in Scutellaria baicalensis.

This study investigates the synthesis of aromatic nitriles using an evolved variant of OxdF1 (L318F/F306Y), an aldoxime dehydratase from Pseudomonas putida F1, engineered for improved catalytic efficiency toward benzaldehyde oxime. The double OxdF1 (L318F/F306Y) mutant effectively catalyzes the conversion of various benzaldoxime derivatives to the corresponding nitriles. Due to the enzyme's inherent instability, immobilized whole-cell systems are employed in a flow reactor to improve its stability and broaden its applicability, with the biotransformation of benzaldehyde oxime and 2,6-difluorobenzaldehyde oxime serving as case studies.

Background And Aims: Cholangiopathies, including primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC), and post-COVID-19 cholangiopathy (PCC), involve chronic cholangiocyte injury, senescence, epithelial-stromal crosstalk, and progressive fibrosis. However, effective in vitro models to capture these interactions are limited. Here, we present a scaffold-free 3D multilineage spheroid model, composed of hepatocyte-like cells (HepG2), cholangiocytes (H69), and hepatic stellate cells (LX-2), designed to recapitulate early fibrogenic responses driven by senescent cholangiocytes.
