Research goals

Salivary biochemistry. Saliva is a multifunctional and complex body fluid that exerts host-protective effects. I am interested in how specific salivary proteins can protect individuals from oral infectious diseases. Studies are ongoing attempting to quantify protein levels among subjects and correlate them with salivary microbial profiles.

Epithelial cell biology. One of the consequences of periodontal disease is an altered gingival epithelium. I am interested in how inflammation alters epithelial cell behavior, in particular the cell-cell and cell-substrate attachment mechanisms.

Clinical diagnosis and treatment of oral diseases. I am interested in understanding the risk factors associated with oral conditions as well as evaluating the results of clinical treatments.

Separation of salivary histatins by capillary electrophoresis. Human parotid saliva sample was acidified, heated, centrifuged and the resulting supernatant analyzed at 20 kV and 24oC on a Hewlett Packard CE apparatus (model HP-G1600/AX) in 0.05 M sodium phosphate buffer, pH 2.5. Sample was injected 5 sec under pressure into a 50 ┬Ám x 75 cm silica capillary with protein detection at 214 nm. Purified histatins were used as standards to identify and quantify the CE peaks corresponding to the major Histatins 1, 3 & 5 Leone C, et al, J Dent Res 80:520 abst 2001.
