Pro-inflammatory effects of inhaled Great Salt Lake dust particles by Jacob M. Cowley, Cassandra E. Deering-Rice, John G. Lamb, Erin G. Romero, Marysol Almestica-Roberts, Samantha N. Serna, Lili Sun, Kerry E. Kelly, Ross T. Whitaker, Jenna Cheminant, Alessandro Venosa, Christopher A. Reilly

“…Pro-inflammatory biomarker mRNA induction was replicated in vitro using HBEC3-KT and differentiated monocyte-derived (macrophage-like) THP-1 cells. In HBEC3-KT cells, IL6 and IL8 (the human analogue of Cxcl1 and Cxcl2) mRNA induction was attenuated by ethylene glycol-bis(β-aminoethyl ether)-N, N,N′,N’-tetraacetic acid (EGTA) and ruthenium red (RR) co-treatment, and by TRPV1 and TRPV3 antagonists, but less by the Toll-like Receptor-4 (TLR4) inhibitor TAK-242 and deferoxamine. …”

Novel predictive biomarkers for atonic postpartum hemorrhage as explored by proteomics and metabolomics by Jiangxue Qu, Hai Jiang, Huifeng Shi, Nana Huang, Jiawen Su, Yan Zhang, Lian Chen, Yangyu Zhao

“…Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) functional enrichment analysis of significantly differentially expressed proteins revealed that atonic PPH was associated with T cell- and macrophage-related immune inflammatory responses. Furthermore, we verified that concentrations of histidine (350.85 ± 207.87 vs. 648.33 ± 400.87) and DPYD (4.01 ± 2.56 vs. 10.96 ± 10.71), and immune cell-related proteins such as CD163 (0.29 ± 0.19 vs. 1.51 ± 0.83) and FGL2 (5.98 ± 4.23 vs. 11.37 ± 9.42) were significantly lower in the PPH group. …”

Vectorized Treg-depleting αCTLA-4 elicits antigen cross-presentation and CD8+ T cell immunity to reject ‘cold’ tumors by Laetitia Fend, Eric Quemeneur, Monika Semmrich, Jean-Baptiste Marchand, Matilda Rehn, Nathalie Silvestre, Linda Mårtensson, Johann Foloppe, Ingrid Teige, Björn Frendeus, Petra Holmkvist, Carolin Svensson, Christelle Remy, Patricia Kleinpeter, Jules Deforges, Fred Junghus, Kirstie L Cleary, Mimoza Bodén

“…A tumor-selective oncolytic vaccinia vector was then engineered to encode this novel, strongly Treg-depleting, checkpoint-blocking, αCTLA-4 antibody or a matching surrogate antibody, and Granulocyte-macrophage colony-stimulating factor (GM-CSF) (VVGM-αCTLA-4).Results The identified 4-E03 antibody showed significantly stronger Treg depletion, but equipotent checkpoint blockade, compared with clinically validated αCTLA-4 ipilimumab against CTLA-4-expressing Treg cells in a humanized mouse model in vivo. …”
