  • Title: Acid phosphatase activity in mouse brain infected with Venezuelan equine encephalomyelitis virus.
    Author: Garcia-Tamayo J.
    Journal: J Virol; 1971 Aug; 8(2):232-41. PubMed ID: 4107246.
    Abstract:
    The mode of development of Venezuelan equine encephalomyelitis virus and the activity of acid phosphatase in the central nervous system of newborn mice were investigated. Precursor particles appeared to be formed in masses of viroplasm, migrating to the membrane of the Golgi cisterns and vacuoles or to the plasma membrane and being transformed into mature viral particles by budding. Mature viral particles were also found in the lumen of the blood vessels and around the myelin sheath of axons. Increased number of Golgi complexes and depletion of polysomes were the main ultrastructural alterations of the nerve cells. Acid phosphatase activity was found to be increased in the Golgi cisterns, vacuoles, and lysosomes of nerve cells. The presence of acid phosphatase activity in the rough endoplasmic reticulum and perinuclear cisterns suggests increased production of the enzyme in the nerve cells infected with Venezuelan equine encephalomyelitis virus.
