Structure and expression of proteolipid protein in the peripheral nervous system

Abstract: Proteolipid protein (PLP), the major myelin protein in the central nervous system (CNS), is also made by Schwann cells (SC) in the peripheral nervous system (PNS) but is not incorporated into the SC myelin sheath. We analyzed several PLP cDNA clones isolated from a rat sciatic nerve cDNA library and found that their coding sequences were identical to PLP cDNAs previously isolated from the CNS. In addition, we have discovered an unusual form of PLP message, present in both brain and sciatic nerve RNA, that is l… Show more

“…Expression of MOBP outside the CNS has not been observed (23,24). In contrast, the MSassociated autoantigens MBP and PLP both are expressed by oligodendrocytes, but also in the peripheral nervous system (52)(53)(54) as well as by cells in the thymus (55). In agreement with the CNSspecific expression of MOBP, we do not detect mononuclear cell infiltration in peripheral organs or the peripheral nervous system after inoculation of SJL/J mice with the encephalitogenic MOBP peptide pool.…”

“…PLP, for instance, is only expressed at low levels in Schwann cells, which constitute the myelinating cells of the peripheral nervous system. Furthermore, PLP is not integrated into Schwann cell myelin (16). In the central nervous system, however, PLP accounts for approximately 40% of total myelin protein, and PLP transcripts are highly abundant in oligodendrocytes, which are the myelinating cells of the central nervous system.…”

“…This idea suggests that some product of the DM20/PLP gene is a trophic factor, or is involved in the transfer of trophic factors to ASs. Other functional PLP gene products may remain to be de scribed, since alternative splicing has recently been demonstrated in the 3'-untranslated region of the prim ary PLP transcript [29]. Thus, the key to understanding how the jp mutation effects AS function and metabolism may not involve myelin PLP at all, but may be due to another product of the PLP gene with a completely dif ferent function.…”
