Exploring the role of T cells in the ADNP deficiency model of syndromic autism. 01/01/2024 - 31/12/2027

Abstract

Loss-function mutations in the Activity-dependent neuroprotective protein (ADNP) gene have been linked to the Helsmoortel-Van der Aa Syndrome, a complex neurological disorder characterized by autism and intellectual disability. The Adnp mutant mice recapitulate key hallmark of autism spectrum disorders including learning deficit, increased anxiety and repetitive behavior. ADNP is involved in brain development and neuroprotection. In addition to the neuroprotective effect, ADNP also has immunomodulatory effects. ADNP is expressed in cells of the immune system and can suppress the production of pro-inflammatory cytokines. Studies in Multiple Sclerosis have linked ADNP deficiency to reduced regulatory T cell function, an immunomodulatory subset of T cells. A better understanding of the immune changes associated with ADNP deficiency may provide clues to pathological processes and allow to identify biological markers that enable early diagnosis and treatment of ASD. In this project, we will explore the role of ADNP in T cells function, to this end will perform in depth characterization of the molecular and cellular signature acquired by T cells and microglia cell populations in the mutant mice. We hypothesize that in Adpn mice defective function of Regulatory T cells exacerbate the pathology. We will use a tailored gene therapy to specifically expand Regulatory T cells in the brain and evaluate the effect on the behaviour of the Adpn mutant mice
