This last analysis ratifies that the treatment with Ngb-NPs is involved in some transcendent biological processes, such as endocytosis, protein metabolism, synaptic function, and neurotransmission (synthesis of neurotransmitters—GABA, serotonin, glutamic acid—or synaptic vesicles traffic), or even in molecular pathways recurrent in some neurodegenerative diseases, such as Huntington’s, Parkinson’s, or Alzheimer’s. The gene discussed is NGB; the disease is Parkinson disease.
