Anti-HSV type 2 Monoclonal antibody

Scientific and clinical data indicate that human herpes simplex virus 1 (HSV1) and, at a lesser extent, human herpes simplex virus 2 (HSV2) are factor(s) implicated in the development of erythema multiforme (EM). With a focus on oral EM, the present structured review of proteomic and epitope databases searched for the molecular basis that might link HSV1 and HSV2 infections to EM. It was found that a high number of peptides are shared between the two HSV5 and human proteins related to the oral mucosa. Moreover, a great number of the shared peptides are also present in epitopes that have been experimentally validated as immunopositive in the human host. The results suggest the involvement of HSV infections in the induction of oral EM via a mechanism of auto immune cross-reactivity and, in particular, highlight a potential major role for 180 kDa bullous pemphigoid antigen and HSV1 infection in the genesis of crossreactions potentially conducive to EM.

In 2012, a 50 year-old athletic male presented with weakness, pain and unilateral phrenic paralysis, followed by bilateral phrenic paralysis with deep dyspnea. In 2013, the ParsonageTurner syndrome was diagnosed. When the patient was seen in September 2014 for the first time, he was facing phrenic neuromuscular failure, which led to the hypothesis of neurotropic herpes viruses. A control of the global serological anti-Herpes immunity to analyze his antibody (Ab) levels confirmed herpes immune genetic deficiency. An appropriate herpes chemotherapy treatment was proposed. Immediately, a spectacular recovery of the patient was observed, and after a few weeks, the respiratory function tests showed normal values. The hypothesis of the inductive role of viruses of the herpes family in the Parsonage-Turner syndrome was thus substantiated. The patient's immune deficiency covers the HSV2, HHV3, HHV4, HHV5 and HHV6 Ab levels. This led to the control of herpes in the family lineage: indeed, his daughter presented alterations of her serological herpes Ab levels. (C) 2015 S. Karger AG, Basel
