title: [TNF-alpha binding ability as a sign of peripheral blood neutrophils preactivation in the course of multiple sclerosis].
abstract: Usually neglected is the role of neutrophils in causing of immunological disturbances in patients with multiple sclerosis (MS). Nevertheless, it has been indicated over the recent years that these cells possess a sufficient potential to affect both immune response and inflammation. This potential may result in MS through the process of priming of these cells by proinflammatory cytokines like TNF. We studied TNF and its soluble receptors sp55 and sp75 serum levels and binding of fluorescein isothiocyanate (FITC)-stained TNF by neutrophils. We studied three different groups of MS patients: 10 patients in relapse of the disease, 13 in its remission, and 11 in its chronic progressive form (CP-MS). The control was provided by 14 neurological patients (OND) with non-inflammatory diseases. The performed studies showed higher TNF sp55 and sp75 soluble TNF receptors serum levels in the patients with relapse, comparing with other MS patients and OND. TNF binding by neutrophils of MS patients during relapse was also higher, than other MS patients and OND. These result suggest the preactivation of neutrophils in the relapse of MS.
