Preparation of Monoclonal Antibodies Against Bovine Progesterone.

Preparation of Monoclonal Antibodies Against Bovine Progesterone. Monoclon Antib Immunodiagn Immunother. 2015 Aug;34(4):275-7 Authors: Zheng J, Zhang H, Bao K, Gao W, Xu C, Xia C Abstract Female, 8-week-old BALB/c mice were immunized with the progesterone complete antigen (P4-BSA). Two monoclonal antibodies (MAbs) against P4, named 8G6 and 11A11, were obtained by the lymphocyte hybridoma technique. The titers of the cell culture supernatant and ascitic fluid of MAb 8G6 were 1: 16,000 and 1:512,000, respectively, and the titers of the cell culture supernatant and ascitic fluid of MAb 11A11 were 1: 8000 and 1:256,000, respectively. The subtypes of the MAbs 8G6 and 11A11 were IgMκ. In specific analysis, both of the two MAbs did not react with estradiol. These data demonstrated that the MAbs 8G6 and 11A11 have a potential use for developing diagnostic reagents of progesterone. PMID: 26301932 [PubMed - in process]

In recent years, SHP2 has been the focus of significant attention in human diseases, particular in cancer. Several studies have shown that SHP2 plays an important role in regulating immune cell functions in tumor microenvironment. A few clinical trials conducted using SHP2 allosteric inhibitors have shown remarkable anti-tumor benefits an...

Autoimmune hypothalamic-pituitary-adrenal axis (HPA) diseases induced by checkpoint inhibitors are being increasingly recognized. We aimed to characterize the spectrum of checkpoi...

Authors: Reck M, Shankar G, Lee A, Coleman S, McCleland M, Papadimitrakopoulou VA, Socinski MA, Sandler A Abstract Introduction: Cancer immunotherapy has revolutionized the treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC). However, specific patient groups (e.g. patients with activating epidermal growth factor receptor [EGFR] mutations) do not appear to derive benefit from immune checkpoint inhibitor (ICI) monotherapy. Combining ICIs, such as atezolizumab, with chemotherapy and/or targeted therapies may help to address this unmet need.Areas covered: Atezolizumab is an anti-program...

Govea Alonso, Sergio Rosales-MendozaAbstractSynucleinopathies are conditions that remain with no available effective treatments thus far. Immunotherapy is a possible path to fight against such pathologies by inducing antibodies against alpha-synuclein (α-Syn), which could induce the clearance of its pathologic form. Looking to develop a new low-cost, effective vaccine against synucleinopathies; we have designed a chimeric plant-made antigen comprising the subunit B of the enterotoxin fro...

             Basel, 13 December 2019 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced the Phase III IMspire150 study, in people with previously untreated BRAF V600 mutation-positive advanced melanoma, met its primary endpoint of progression-free survival (PFS). The study showed adding Tecentriq ® (atezolizumab) to Cotellic® (cobimetinib) and Zelboraf® (vemurafenib) helped to reduce the risk of disease worsening or death, compared to placebo plus Cotellic and Zelboraf. A significant and clinically meaningful improvement in PFS was demonstrated in the study. The safety ...

Genetic alterations can directly influence the nature of cancer cells in the native tumor microenvironment to mediate immune escape. Our genome-scale in vivo CRISPR screens robustly identified multiple regulators of tumor-intrinsic factors that alter the ability of cells to grow as tumors across different levels of immunocompetence. As a convergent hit from these screens, Prkar1a mutant cells are able to...
