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.

Extracapsular Dissection Versus Traditional Parotid Surgery: A Comprehensive Review of Techniques and Outcomes.

Parotid tumours, encompassing both benign and malignant forms, present significant challenges in surgical management. Traditional parotid surgery, including various forms of parotidectomy, has long been the standard approach, aiming for complete tumour removal while addressing potential complications such as facial nerve injury. However, extracapsular dissection (ECD) has emerged as an alternative technique, focusing on excising the tumour along with a thin layer of surrounding tissue, which may offer benefits in preserving healthy glandular tissue and reducing postoperative complications.

Polybodies: Next-generation clinical antibodies.

Conventional antibodies [full-length and fragments: F(ab'), fragment antigen-binding (Fab), single-chain variable fragment (scFv), variable heavy domain of heavy chain antibody (VHH)] are monospecific, first-generation antibodies, that have dominated the biopharmaceuticals field. However, protein engineering approaches has led to the advent of the next-generation antibodies (polybodies), which are significant improvement over the conventional antibodies. Polybodies comprise polyspecific and/or polyvalent antibodies that enable a single antibody to target multiple specific antigens simultaneously.

Loop Diuretics Unique Mechanism of Action.

Loop diuretics, including torsemide, furosemide, bumetanide, and piretanide, act by inhibiting the sodium-potassium-chloride (Na/K/2Cl) cotransporter in the thick ascending limb of the loop of Henle within the nephron. This mechanism is pivotal in managing fluid retention associated with conditions such as heart failure, cirrhosis, chronic kidney disease, and hypertension. A comprehensive understanding of how these diuretics uniquely target this transporter provides crucial insights into effectively addressing fluid overload across diverse clinical conditions.
