Drug hypersensitivity (DH) reactions are clinically unusual because the underlying immune stimulations are not antigen-driven. but due to non-covalent drug-protein binding. The drugs may bind to immune receptors like HLA or TCR which elicits a strong T cell reaction (p-i concept). the binding may enhance the affinity of antibodies (enhanced affinity model). https://www.bekindtopets.com/limited-offer-Silver-Lining-Herbs-Kidney-Support-super-offer/
