Abstract
Lysosomal diseases comprise a group of inherited disorders resulting from defects of lysosomal enzymes and their cofactors, and in many of them the nervous system is affected. Recently, enzyme replacement therapy with recombinant lysosomal enzymes has been clinically available for several lysosomal diseases. Such enzyme replacement therapies can improve non-neurological disorders but is not effective for neurological ones. In this review, we discuss the molecular pathologies of lysosomal diseases from the protein structural aspect, current enzyme replacement therapies, and attempts to develop enzyme replacement therapies effective for lysosomal diseases associated with neurological disorders, i.e., production of enzymes, brain-specific delivery and incorporation of lysosomal enzymes into cells.

Diagnosis and treatment of central nervous system infectious diseases
Infectious diseases of the central nervous system (CNS) can be divided into bacterial, tuberculous, viral, fungal, parasitic infections, etc. Early etiological treatment is often the most crucial means to reduce the mortality rate of patients with central nervous system infections, reduce complications and sequelae, and improve prognosis. The initial clinical ...read more
