“…Given these findings, the development of subunit vaccines against RSV appears more promising. Several RSV subunit vaccine formulations have been examined, including purified F protein (PFP) vaccines (4,5,18,23,35,44), and those targeting G protein. For example, BBG2Na is a G-protein subunit vaccine candidate that was shown to elicit robust immune responses in small and large animals (8,14,55), and has been evaluated in human clinical trials.…”

Respiratory syncytial virus (RSV) is a primary cause of severe lower respiratory tract disease in infants, young children, and the elderly worldwide, and despite decades of effort, there remains no safe and effective vaccine. RSV modifies the host immune response during infection by CX3C chemokine mimicry adversely affecting pulmonary leukocyte chemotaxis and CX3CR1+ RSV-specific T-cell responses. In this study we investigated whether immunization of mice with RSV G protein polypeptides from strain A2 could induce antibodies that block G protein-CX3CR1 interactions of both RSV A and B strains. The results show that mice immunized with RSV A2 G polypeptides generate antibodies that block binding of RSV A2 and B1 native G proteins to CX3CR1, and that these antibodies effectively cross-neutralize both A and B strains of RSV. These findings suggest that vaccines that induce RSV G protein-CX3CR1 blocking antibodies may provide a disease intervention strategy in the efforts to develop safe and efficacious RSV vaccines.

B Cell Epitope-Based Vaccination Therapy

Currently, many peptide vaccines are undergoing clinical studies. Most of these vaccines were developed to activate cytotoxic T cells; however, the response is not robust. Unlike vaccines, anti-cancer antibodies based on passive immunity have been approved as a standard treatment. Since passive immunity is more effective in tumor treatment, the evidence suggests that limited B cell epitope-based peptide vaccines may have similar activity. Nevertheless, such peptide vaccines have not been intensively developed primarily because humoral immunity is thought to be preferable to cancer progression. B cells secrete cytokines, which suppress immune functions. This review discusses the possibility of therapeutic antibody induction by a peptide vaccine and the role of active and passive B cell immunity in cancer patients. We also discuss the use of humanized mice as a pre-clinical model. The necessity of a better understanding of the activity of B cells in cancer is also discussed.

Current Mass Spectrometric Tools for the Bioanalyses of Therapeutic Monoclonal Antibodies and Antibody-Drug Conjugates

et al. 2018

The increase in the use of therapeutic monoclonal antibodies (mAbs) and antibody-drug conjugates (ADCs) has made the detailed bioanalysis of these drugs essential not only for planning optimal therapeutic programs for clinical practice, but also for evaluating the biological equivalencies in the development of other biosimilars. The ligand binding assays that are widely in use now are being replaced rapidly by the highly accurate, sensitive, and selective analytical method using a mass spectrometer. This review will discuss the progress in and challenges observed during the development of a mass spectrometry-based bioanalytical method for therapeutic mAbs and ADCs.
