Besides, nuclear HDAC4 distribution was enhanced in Purkinje neurons from Atm-deficient mice after lipopolysaccharides (LPS) stimulation, and Atm was identified to be involved in ataxia-telangiectasia characterized by immune deficiency [32], indicating that HDAC4 may directly or indirectly regulate inflammation genes. Here, HDAC4 is linked to Immunodeficiency.
