“…Expression of HERV-related genetic information and its involvement in human pathological processes are mostly unknown and under active investigation. There are numerous publications describing HERV activation in different types of cancer (addressed in this review), as well as in other diseases such as type 1 diabetes ( Levet et al., 2017 ), neurological diseases such as multiple sclerosis (MS) ( Perron et al., 2012a ; Madeira et al., 2016 ; Hartung et al., 2022 ; Irfan et al., 2022 ) and amyotrophic lateral sclerosis (ALS) ( Douville et al., 2011 ; Alfahad and Nath, 2013 ; Arru et al., 2021 ; Phan et al., 2021 ), and psychiatric diseases such as schizophrenia ( Aftab et al., 2016 ; Perron et al, 2012b ; Tamouza et al., 2021 ) and bipolar disorder ( Perron et al., 2012b ; Tamouza et al., 2021 ). Over the last few years, research in this field has led to growing interest in exploring HERV-originated products as biomarkers for disease and specific HERV-derived antigens as targets for immunotherapy.…”
