Classical viral vaccines rely on the induction of neutralizing antibodies. In the case of infection by the human immunodeficiency virus (HIV), the viral spike has evolved to evade recognition by these antibodies. Despite these obstacles, certain monoclonal antibodies capable of neutralizing the majority of primary HIV-1 isolates have been successfully isolated and have demonstrated efficacy both in controlling viremia and in providing protection against infection in animal models. These are known as broadly neutralizing antibodies (bNAbs).
In order to identify the factors involved in the induction of these antibodies and to develop preventive strategies based on bNAb induction, we are pursuing the following research lines:
- Determination of factors associated with the induction of effective humoral responses in different scenarios: recent infection, chronic infection, co-infection with hepatitis C virus, reinfection, and pediatric infection, among others.
- Study of the effect of feminizing hormone therapy on the immune system of transgender women.
- Development of HIV-1 vaccine prototypes based on viral spike proteins incorporated into Virus-Like Particles (VLPs) from two sources:
a) Selected from a library of randomly mutated spikes to enhance the accessibility of epitopes recognized by bNAbs.
b) Derived from viruses present in individuals with broad neutralizing responses in recent infection. - Isolation and characterization of new bNAbs against HIV-1 from individual B cells of individuals with an efficient neutralizing response. These antibodies could be used in both preventive and therapeutic strategies.
- Isolation of new monoclonal antibodies against other human pathogenic viruses, adapting the technology developed for HIV-1 antibody isolation, in collaboration with researchers from the National Center for Microbiology.
- Use of gene therapy vectors (Recombinant Adeno-Associated Viruses; rAAVs) to incorporate bNAbs and apply them in prophylactic and therapeutic strategies.
