Schwannomatosis (SWN) is a genetic disorder that predisposes affected individuals to develop multiple Schwannomas anywhere in the peripheral nervous system. This can be due to a mutation in the LZTR1 or SMARCB1 genes on chromosome 22. SWN has the defining clinical symptom of chronic pain and a lack of vestibular schwannomas, which sets it apart from other, related disorders such as Neurofibromatosis Type II (NF2). Currently, it is unknown what causes the chronic pain of SWN patients but it is hypothesized that cytokines may have promote the neuropathic pain experienced by patients. This study investigates the presence of the chemokine CCL2 and the cytokine IL6 in human SWN schwannomas and non-SWN schwannomas to determine if there is a difference in the presence of these cytokines between the two tumor types. It was demonstrated that all of the SWN schwannomas expressed both CCL2 and IL6 whereas the non-SWN schwannomas expressed only one or the other protein if either. These results indicate that the presence of these cytokines within the SWN schwannomas is different from non-SWN schwannomas and could be a potential contributing factor in the occurrence of neuropathic pain experienced by SWN which is part of the differential diagnosis for NF2 and SWN.
