Potential of Phage Display Antibody Technology for Cardiovascular Disease Immunotherapy

Harnessing filamentous phages for enhanced stroke recovery

Stroke poses a critical global health challenge, leading to substantial morbidity and mortality. Existing treatments often miss vital timeframes and encounter limitations due to adverse effects, prompting the pursuit of innovative approaches to restore compromised brain function. This review explores the potential of filamentous phages in enhancing stroke recovery. Initially antimicrobial-centric, bacteriophage therapy has evolved into a regenerative solution. We explore the diverse role of filamentous phages in post-stroke neurological restoration, emphasizing their ability to integrate peptides into phage coat proteins, thereby facilitating recovery. Experimental evidence supports their efficacy in alleviating post-stroke complications, immune modulation, and tissue regeneration. However, rigorous clinical validation is essential to address challenges like dosing and administration routes. Additionally, genetic modification enhances their potential as injectable biomaterials for complex brain tissue issues. This review emphasizes innovative strategies and the capacity of filamentous phages to contribute to enhanced stroke recovery, as opposed to serving as standalone treatment, particularly in addressing stroke-induced brain tissue damage.

Generation of a Naïve Human scFv Phage Display Library and Panning Selection

Phage display antibody libraries have been successfully used as the essential tool to produce monoclonal antibodies against a plethora of targets ranging from diseases to native biologically important proteins as well as small molecules. It is well documented that diverse antibody genes are the major genetic source for the construction of a high-quality antibody library and selection of high-affinity antibodies. Naïve antibody libraries are derived using the IgM repertoire of healthy donors obtained from B-cells isolated from human peripheral blood mononuclear cell (PBMC). Single-chain fragment variable (scFv) is a routinely used format due to its smaller size and preference for phage display. The process involves the use of a two-step cloning method for library construction. The protocol also covers the biopanning process for target positive clone selection.

Unlocking the Potential of Immunotherapy in Cardiovascular Disease: A Comprehensive Review of Applications and Future Directions

Immunotherapy has emerged as a pioneering therapeutic approach that harnesses the immune system's abilities to combat diseases, particularly in the field of oncology where it has led to significant advancements. However, despite its significant impact in the field of oncology, the potential of immunotherapy in the context of cardiovascular disease (CVD) has not been thoroughly investigated. The purpose of this narrative review is to address the existing knowledge and potential uses of immunotherapy in the field of cardiovascular disease (CVD), with the intention of filling the existing gap in understanding. Furthermore, the review thoroughly examines the future prospects of this swiftly advancing field, providing insights into the aspects that necessitate further investigation and addressing the forthcoming challenges. The review is organized into four distinct sections to enhance comprehension. The first section introduces immunotherapy, presenting the fundamental concepts and principles. The second section explores the immunomodulatory mechanisms in cardiovascular disease (CVD), with a specific focus on the intricate interplay between the immune system and the development of cardiovascular pathogenesis. The utilization of immunotherapy in specific cardiovascular conditions will be examined, investigating the application of immunotherapy in the context of different cardiovascular diseases. The future prospects and challenges in immunotherapy for cardiovascular diseases will be discussed, highlighting the potential areas for future research and addressing the barriers that must be overcome to effectively implement immunotherapeutic interventions in the management of cardiovascular diseases.
