Apolipoprotein L4 (APOL4)

Apolipoprotein L4 (APOL4) is a member of the apolipoprotein L family primarily involved in lipid transport and immune regulation. It is encoded by a gene on human chromosome 22 and shares structural motifs with other apolipoprotein L family members, suggesting roles in both lipid metabolism and innate immune function[2]. APOL4 is expressed across multiple tissues, including brain, liver, and immune cells, and is implicated in reverse cholesterol transport and lipid exchange[2]. Recent computational and experimental studies suggest that APOL4 is involved in immune signaling, inflammatory pathways, and neurodevelopmental processes, and may function as an immune-related biomarker in central nervous system diseases such as schizophrenia and glioma[1][2][3]. Disease association studies have implicated APOL4 in several disorders, including 22q11.2 deletion syndrome, Velocardiofacial syndrome, Hyperprolinemia type 1, and cancers such as glioma, where its elevated expression is associated with a poorer prognosis[1][3]. Although APOL4’s function is less well characterized compared to other apolipoprotein L family proteins, current evidence suggests multifaceted roles spanning lipid metabolism, neurotransmission, immune regulation, and disease pathology[1][2][3].
