Abstract:
The function of Class II molecules in proliferation was explored by treating human cell lines with three distinct anti-DR monoclonal antibodies (MABs). Dose-dependent, specific inhibition of eight DR+ cell lines of different origin and lineage was found. Inhibition was durable (i.e., cells did not become resistant to the anti-DR MABs despite prolonged treatment) yet reversible. The mechanism of inhibition was not due to differentiation or killing but was cytostatic. Inhibition was temporally associated with decreases in nuclear size and irregularity and appeared to be due to a non-phase-specific cell cycle arrest.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
