Monoclonal antibodies (mAbs) are used as immunotherapeutics to treat cancer and other diseases, and either aim to induce target cell destruction or immune cell activation. After binding to their cognate antigens, mAbs engage Fc gamma receptor (FcγR), localised on the surface of the Immune cells, and identified by many research groups as regulator of mAbs activity. To help researchers working on immunotherapeutic mAbs development, BPS Bioscience have developed a new CHO K1 cell line stably expressing full length human FcGR2B.
Mass spectrometry is a technology which is widely used in most scientific disciplines that require accurate and precise measurement of elemental and molecular components. Its use in the pharmaceutical sector is often associated with the Drug Discovery and Development process. The primordial step to analyze a sample is to perform a sample treatment to enable its study. It really requires know-how to obtain good quality results. The following tips and tricks can help you to rapidly select a protein purification strategy and to anticipate some possible problems.
mRNA vaccines are developing very quickly. There are already 25 ongoing clinical trials against cancers, as well as clinical trials against infectious diseases such as HIV. Recombinant monoclonal antibody (mAB) based treatments that have lead to the most successful therapies could even switch to mRNA coding heavy and light chains for direct antibody production into the patient (as of yet still at the level of mouse models).
Indeed, messenger RNAs (mRNA) are now new biological entities to take in consideration for the development of efficient and personalized therapies. They have several advantages over conventional drugs:
As a regulator of the immune system, Immune checkpoints appear to be privileged targets In Drug Discovery and Immunotherapy research. Indeed, promising molecules tested in clinical trials and approved are giving new hope for cancer treatment. Beyond checkpoint receptors, the Enzymatic pathway also regulates the immune system and provides additional targets for Drug Development, and may increase the chances of clinical success in Cancer treatment.
In addition to already developed Immune Checkpoint Reporter cell lines (as introduced in my previous post), BPS Bioscience also provide tools to study the enzymatic pathway, such as the tryptophan catabolism pathway controlled by IDO1: The IDO / TDO pathway.
