OBJECTIVE To investigate the salivary protein profile in patients with Sjögren's syndrome (SS), and healthy control subjects. MATERIALS AND METHODS Unstimulated whole saliva samples were collected from 16 age-matched females; eight healthy subjects and eight patients diagnosed with SS (six primary SS, one incomplete SS and one primary SS associated with B(More)
Proteomic characterization of human whole saliva for the identification of disease-specific biomarkers is guaranteed to be an easy-to-use and powerful diagnostic tool for defining the onset, progression and prognosis of human systemic diseases and, in particular, oral diseases. The high abundance of proteins, mainly alpha amylase, hampers the detection of(More)
OBJECTIVE SS is an autoimmune exocrinopathy affecting ∼1 million patients in the USA that is diagnosed mostly in middle-aged women. Oral fluids (OFs) serving as the mirror of the body were suggested as an ideal non-invasive diagnostic tool. Previously we developed depletion techniques for OF high-abundance proteins to increase visualization of low-abundance(More)
BACKGROUND Recently, interest in finding disease bio-markers in human body fluids including oral fluids (OF), mainly saliva has increased. However, the physiologic differences in salivary proteins according to gender and age should be explored to establish a clinical diagnostic tool. OBJECTIVE To compare OF protein expression according to gender and age,(More)
Oral fluids (OF) have been suggested as a source of biomarkers for oral and systemic health, but as with other bio-fluids, the presence of high-abundance proteins interferes with the detection of lower-abundance biomarkers. Here, we compared the performance of four depletion treatments: triple depletion (TD) of amylases, albumins and immunoglobulin G;(More)
YAC is a Moloney-virus-induced tumor of A mice. YAC-injected A and C57BL/6 mice generated suppressor cells. The suppressive function of the cells was tested by determining the ability of splenocytes from YAC-injected mice to inhibit the in vitro cytotoxic responses of primed splenocytes. It was found that suppressor cells passed through a nylon-wool column(More)
OBJECTIVES (i) To determine whether salivary cortisol and electrolyte levels differ between patients with Sjogren's syndrome (SjS) and healthy individuals. (ii) To assess correlations between whole-saliva cortisol and some clinical manifestations in patients with SjS. METHODS A total of 24 healthy women (mean age 49.3±9.8) served as controls (C) vis-à-vis(More)
OBJECTIVES The aim of this study was to examine whether triple depletion of salivary-α-amylase (sAA), albumin (Alb) and immunoglobulins G (IgGs) may improve the visualization capability of proteins in two-dimensional gel electrophoresis (2-DE) of oral fluids (OF). SUBJECTS AND METHODS Oral fluids from healthy volunteers were subjected sequentially to sAA(More)
Unprimed spleen cells from A and C57BL/6 mice could not produce cytotoxic responses to their syngeneic tumors: a Moloney virus-induced in vitro subline YAC-1 and a Rauscher virus-induced in vitro subline RBL5, respectively. Spleen cells from A and C57BL/6 mice immunized with YAC-1 OR RBL5 (which cross-react serologically) generated significant syngeneic(More)
