PLIN2 and viral infectious disease: This insufficiencypotentially stems from its dependence on viral infection context, requiringadditional viral factors, cooperative signaling pathways, an altered cellular state,or some unknown autocrine/paracrine effects that are present during virus infection.The differential effects of the VGF peptide on PLIN2, neutral lipid droplets, andACLY phosphorylation likely reflect the involvement of distinct mechanisms orsignaling pathways, with PLIN2 regulation being more directly influenced by VGF,while ACLY phosphorylation requires a more complex set of conditions orinteractions.
