A virus-like particle-based vaccine selectively targeting soluble TNF-alpha protects from arthritis without inducing reactivation of latent tuberculosis.
- Abstract:
- Neutralization of the proinflammatory cytokine TNF-alpha by mAbs or soluble receptors represents an effective treatment for chronic inflammatory disorders such as rheumatoid arthritis, psoriasis, or Crohn's disease. In this study, we describe a novel active immunization approach against TNF-alpha, which results in the induction of high titers of therapeutically active autoantibodies. Immunization of mice with virus-like particles of the bacteriophage Qbeta covalently linked to either the entire soluble TNF-alpha protein (Qbeta-C-TNF(1-156)) or a 20-aa peptide derived from its N terminus (Qbeta-C-TNF(4-23)) yielded specific Abs, which protected from clinical signs of inflammation in a murine model of rheumatoid arthritis. Whereas mice immunized with Qbeta-C-TNF(1-156) showed increased susceptibility to Listeria monocytogenes infection and enhanced reactivation of latent Mycobacterium tuberculosis, mice immunized with Qbeta-C-TNF(4-23) were not immunocompromised with respect to infection with these pathogens. This difference was attributed to recognition of both transmembrane and soluble TNF-alpha by Abs elicited by Qbeta-C-TNF(1-156), and a selective recognition of only soluble TNF-alpha by Abs raised by Qbeta-C-TNF(4-23). Thus, by specifically targeting soluble TNF-alpha, Qbeta-C-TNF(4-23) immunization has the potential to become an effective and safe therapy against inflammatory disorders, which might overcome the risk of opportunistic infections associated with the currently available TNF-alpha antagonists.
