The role of enzymatic coupling of drugs to proteins in induction of drug specific antibodies

The Journal of Investigative Dermatology

Abstract

Isoniazid and hydralazine were covalently crosslinked by epidermal transglutaminase to serum and cell nuclear proteins. Albumin and nucleohistones were excellent acceptors of these drugs in serum and nuclear extracts, respectively. Drug-albumin and drug-histone conjugates were highly antigenic in rabbits within 4 weeks, eliciting drug-specific antibodies in all immunized animals. A radioimmunoassay for antibodies to isoniazid were developed, using a standard drug-albumin conjugate. The methods described here of enzymatic crosslinking of drugs to proteins facilitate studies of drug-induced hypersensitivity in animals and man.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
