Marker Sequences for Diagnosing and Stratifying Systemic Sclerosis Patients

Budde, Petra
Jan 2021
The present invention relates to methods for identifying markers for systemic sclerosis (also scleroderma; SSc) and to the markers identified with the aid of this method, which can differentiate between SSc and other autoimmune diseases on the one hand and between different SSc subgroups on the other hand. The invention also relates to panels, diagnostic devices and test kits which comprise these markers, and to the use and application thereof, for example for the diagnosis, prognosis and therapy control of SSc. The invention also relates to methods for screening and for validating active substances for use in SSc.

Histatins are human salivary gland peptides with anti-microbial and anti-inflammatory activities. In this study, we hypothesized that histatin 5 binds to Porphyromonas gingivalis hemagglutinin B (HagB) and attenuates HagB-induced chemokine responses in human myeloid dendritic cells. Histatin 5 bound to immobilized HagB in a surface plasmon resonance (SPR) spectroscopy-based biosensor system. SPR spectroscopy kinetic and equilibrium analyses, protein microarray studies and I-TASSER structural modeling studies all demonstrated two histatin 5 binding sites on HagB. One site had a stronger affinity with a KD1 of 1.9 μM and one site had a weaker affinity with a KD2 of 60.0 μM. Binding has biological implications and predictive modeling studies and exposure of dendritic cells both demonstrated that 20.0 μM histatin 5 attenuated (p < 0.05) 0.02 μM HagB-induced CCL3/MIP-1α, CCL4/MIP-1β and TNFα responses. Thus histatin 5 is capable of attenuating chemokine responses, which may help control oral inflammation.
