Aspartoacylase Deficiency in the White Matter of Human Immunodeficiency Virus Encephalitis : Novel Mechanism in Axonal Damage

Abstract EN

Aspartoacylase/aminoacylase II (ASPA/ACY II) is mainly synthesized in oligodendrocytes to contribute in myelin synthesis.

Although axonal damage is seen in the brain with human immunodeficiency virus encephalitis (HIVE), ASPA contribution in the pathology is not known.

Immunostaining study showed that ASPA protein is reduced in the white matter of patients with HIVE compared to the control.

Western blot study further confirmed ASPA deficiency in the HIVE brain compared to the control.

This paper suggests that HIVE condition affects ASPA to contribute in myelin loss/axonal damage seen in the disease.
