- The major research interests of the team LOMONTE are:
- The study of the pathological consequences of the infection of neurons from the peripheral and central nervous systems by the neurotropic virus herpes simplex virus 1 (HSV-1). We essentially focus our research on the establishment of latency and reactivation processes.
- The study of the implication of nuclear architecture, especially promyelocytic leukemia nuclear bodies (PML NBs), in the regulation of latent HSV-1 chromatin features and in chromatin dynamics during the process of senescence.
- The study of the chromatin alterations associated to damage or to genetic pathologies, and potentially linked to genetic instabilities, or motoneurons decay.

PROJECTS
Beside the study of the biology of HSV-1, one of the main focus of the team is to understand, at the molecular level and using HSV-1 as a model, some basic aspects of nuclear and chromatin dynamics related to the maintenance of genome integrity and to the regulation of gene expression.
