Previous studies in mice indicated that delayed organogenesis and aberrant cell physiology followed by an increase in acinar cell apoptosis precede chronic focal inflammation in the salivary glands and the manifestation of impaired exocrine gland secretion. In a recent study by Wildenberg and colleagues the authors report aberrant proteolytic activity in the salivary glands of non-obese diabetic mice and the generation of a unique organ-specific 17 kDa fragment of the chemokine and adhesion molecule fractalkine. In the previous issue of Arthritis Research Therapy aberrant proteolytic activity in the salivary glands of non-obese diabetic NOD mice with spontaneous experimental Sjogren s syndrome SS was reported 1 . SS is a rather common systemic autoimmune disease characterized by exocrine gland inflammation and impaired glandular function 2 . The NOD strain has become a commonly used spontaneous model for SS in which several .
