Lymphocytic Choriomeningitis

It is widely known that the arenavirus Lymphocytic choriomeningitis (LCM) poses a grave threat to both immunocompetent and immunodeficient individuals alike. We offer full development services for vaccines and therapeutic agents relating to LCM at our company.

Introduction to Lymphocytic Choriomeningitis

Lymphocytic choriomeningitis virus (LCMV) is an Arenaviridae family zoonotic viral pathogen that is carried by rodents. In humans, this virus is contracted through the wastes or saliva of infected rodents. Following exposure to an infected person, the range of illness one can experience largely varies from no symptoms at all to extremely severe neurological symptoms such as encephalitis or meningitis. Immunocompromised people or expecting mothers are at heightened danger due to the associated fetal LCMV infection or teratogenesis.

Vaccine Development for Lymphocytic Choriomeningitis

Recombinant LCMV Vaccines

It is relevant to the formation of immune responses that reduce the chances of getting a disease. An example is the preclinical studies which showed the generation of cytotoxic multifunctional CD8+ T cells and memory T cells because of the inflammation train that was caused by non-replicating recombinant LCMV (rLCMV) vectors, which are indeed important for viral clearance.

Vector-Based Vaccines

These are termed as vector vaccines because biotechnology exploits a harmless virus to act as a vector that carries parts of LCMV for immune response setup. Such vaccines may also be made by using altered or weakened forms of the viral strains. This includes the rLCMV vector that express model antigens which was demonstrated to be safe and effective in immunodeficient mice.

Therapeutics Development for Lymphocytic Choriomeningitis

Antiviral Therapies

Some advances have been made in devising antiviral therapy for LCMV, predominantly because of the constant negative impacts faced in some populations. The general antiviral, Ribavirin, has been given but with only limited success. In contrast, pyrazinecarboxamide derivative favipiravir proved very beneficial in preclinical models because of its strong antiviral effects by means of survival and considerably reduced viral loads.

Immunotherapies

Immunotherapeutic efforts have also been directed against those specific monoclonal antibodies which neutralize at the same level as the virus. They are, for instance, meant to block some of the protective mechanisms which are normally utilized by the host to defend itself against LCMV. Human monoclonal antibodies that were developed against Lassa virus glycoproteins have been shown to cross-react with LCMV and thus may be of therapeutic value.
