Antigen Specificity: A Fluctuating Aspect in the Development of Clinical Antibodies?

Development of antibodies for clinical use is a complex process involving numerous aspects, with antigen specificity being the most important. Initially, polyclonal antibodies, that can recognize multiple specific and nonspecific antigens (polyreactive), were developed and were very effective in the treatments. Later on, the polyspecificity/polyreactivity of these polyclonal antibodies (binding to multiple antigens) raised concerns about therapeutic efficacy because of their nonspecific interactions and challenges, such as development of immune complexes, batch-to-batch variability.

Human Paraoxonase 1: From Bloodstream Enzyme to Disease Fighter & Therapeutic Intervention.

Human paraoxonase 1 (hPON1) is a Ca2+-dependent metalloenzyme with multifunctional properties. Due to its diverse roles as arylesterase, phosphotriesterase, and lactonase, it plays a significant role in disease conditions. Researchers across the globe have demonstrated different properties of PON1, like anti-oxidant, anti-inflammatory, anti-atherogenic, anti-diabetic, and OPneutralization.

Prevalence of anti-HLA antibodies among live related renal transplant recipients: A retrospective observational study from a tertiary healthcare Center in India.

Aim: Detection of anti-HLA antibodies is crucial for pre-transplant histocompatibility testing, donor selection, and graft survival. The aim of this study was to evaluate the spectrum of anti-HLA antibodies among live related renal transplant recipients from one of the largest transplant centers in north India.

Methods: In this study, retrospective data of transplant workup done in past four years were analyzed using GraphPad Prism 9 Version 9.

Endostatin in disease modulation: From cancer to beyond.

Angiogenesis plays a pivotal role in various pathological conditions, making it a key target in therapeutic development. Anti-angiogenic therapies are gaining traction for their potential in treating a range of angiogenesis-dependent diseases. Among these, endogenous angiogenesis inhibitors, particularly endostatin, have garnered significant attention for their therapeutic potential.
