Article Abstract
Glycoprotein B (gB) serves as the viral fusion protein for herpes simplex virus (HSV), mediating fusion between viral and host membranes resulting in infection. As such, gB represents a potentially critical target for the host immune system with high potential relevance for vaccine design. Here we investigated the mechanisms of protection for a panel of gB-specific monoclonal antibodies (mAb) in a mouse model of neonatal HSV (nHSV) infection. Viral neutralization contributed, but Fc effector functions were critical for mAb-mediated protection against nHSV mortality, depending on dose. Moreover, AAV-mediated expression of a gB-specific mAb in mice provided transgenerational protection against HSV-1 and HSV-2 mortality in their offspring. These findings demonstrate that antibodies targeting gB can serve as potent therapeutics and that they require diverse functional profiles to afford optimal protection, informing vaccine design.

The COVID-19 pandemic, caused by the continuously evolving SARS-CoV-2 virus, has presented persistent global health challenges. As novel variants emerge, many with enhanced transmissibility and immune evasion capabilities, concerns have intensified regarding the efficacy of existing vaccines and therapeutics. This review provides a comprehensive overview of the current landscape of COVID-19 vaccination, including the development and performance of monovalent and bivalent boosters, and examines their effectiveness against newly emerging variants of interest (VOIs) and variants under monitoring (VUMs), such as JN.

The fourth leading cause of cancer-related fatalities in the USA is pancreatic ductal adenocarcinoma (PDAC), a particularly deadly illness that is resistant to immunotherapy. One of the Main Obstacles in cancer research is developing better treatments for PDAC, which has the lowest 5-year survival rate of any malignancy. Anti-CTLA-4, anti-PD-L1, and anti-PD-1 immune checkpoint blockade medications also have poor results in these patients, which may indicate the presence of other immunosuppressive mechanisms in the pancreatic tumor microenvironment (TME).

Colorectal cancer (CRC) remains a major global health burden, necessitating more effective and selective therapeutic approaches. Nanocarrier-based drug delivery systems offer significant advantages by enhancing drug accumulation in tumors, reducing off-target toxicity, and overcoming resistance mechanisms. This review provides a comprehensive overview of recent advancements in nanocarriers for CRC therapy, including passive targeting the enhanced permeability and retention (EPR) effect, and active targeting strategies that exploit specific tumor markers using ligands such as antibodies, peptides, and aptamers.

Despite recent progress within the field of immuno-oncology, immune suppression in the tumor microenvironment, defective antigen presentation, and low levels of tumor-specific T cells are key limitations of current cancer immunotherapies. CD40-targeting immunotherapies hold promises for addressing these limitations across solid tumors. Here, we describe ATOR-4066, a bispecific antibody that targets CD40 and CEACAM5 developed for immunotherapy of cancer using the Neo-X-Prime platform.
