In spite of successful therapeutic neutralization of proinflammatory cytokines in several autoimmune diseases, such therapy is not entirely free of side effects. The main reason relates to the fact that cytokine signaling may have protective components that need to be spared. Several approaches to achieve a less damaging cytokine inhibition are being explored. In our experimental studies we are using bispecific reagents based on VHH-modules from the heavy-chain-only antibodies to limit bioavailability of TNF and IL-6 produced by myeloid cells. After evaluation of their properties in vitro and in vivo we argue that these types of reagents may have an advantage over systemic blockers.
