Moreover, the analysis of the transcript for OCTN-1 and mediatophore, the two proteins responsible for the non-vesicular ACh release, typically expressed in immune cells [10,11], indicated higher OCTN-1 expression in PBMC of MS patients (Figure 3A,B), while the expression of mediatophore did not appear significantly changed (Figure 3A,C). Here, SLC22A4 is linked to myeloid sarcoma.
