Abstract

Protein zero (P0), an integral membrane glycoprotein synthesized by Schwann cells, is the major glycoprotein of peripheral nerve myelin. The predicted disposition of P0 with respect to the membrane bilayer postulates the existence of extracellular and intracellular domains, that mediate compaction of the myelin lamellae. We used in vitro translations programed with sciatic nerve mRNA and cells transfected with a P0 cDNA construct to study the biosynthesis and topology of P0 in the bilayer. The behavior of P0 at the cell surface, when expressed under physiological conditions, was also examined. We have verified the topological predictions of an earlier model, derived from analysis of a P0 cDNA, and provide evidence that the extracellular domain of P0 mediates homotypically cell-cell interactions in the transfectants.

      We have tested this workflow using two scWAT depots (inguinal and axillary) which show slightly different responses to neurotrophic stimuli and browning potential (Blaszkiewicz et al., 2019a). This whole mount technique has been optimized for the pan-neuronal markers PGP9.5 (Thompson et al., 1983; Day and Thompson, 2010) and β3-tubulin (Draberova et al., 2008; Latremoliere et al., 2018); the sympathetic nerve marker, tyrosine hydroxylase (TH) (Shi et al., 2005); markers for sensory innervation that included advillin (AVIL) (Hasegawa et al., 2007; Hunter et al., 2018) and Nav 1.8 (Bird et al., 2013); the myelination marker myelin protein zero (MPZ) (D’Urso et al., 1990); as well as several others. This technique has also been optimized for non-antibody based fluorescent labeling approaches such as nuclear labeling with DAPI and vascular labeling with Isolectin IB4 (IB4).

      In further support of PR functioning with nuclear receptor coactivators, cells of the sciatic nerve of female rats co-express PR and SRC-2, another member of the p160 family (Fig. 3). P0 and PMP22 play an important role for the maintenance of the multilamellar structure of PNS myelin [57]. Therefore, consistent with the effects exerted on the proteins of peripheral myelin, PROG stimulates the synthesis of myelin membranes accelerating the time of initiation and enhancing the rate of myelin synthesis in Schwann cells co-cultured with DRG neurons [19,58].
