The UNC CF Center has developed a number of novel biomarkers for measuring the pharmacodynamic and therapeutic effects of inhaled therapeutic agents in sputum. Much effort has been focused on the measurement of the proper vs. improper hydration of mucus in airway diseases. Consequently, the UNC CF Center has a spectrum of technologies designed to measure these parameters in induced or expectorated sputum, including measures of absolute mucin concentrations, mucin/mucus osmotic pressure/modulus, and measures of mucus adhesion (see Figure 21). In parallel, the UNC CF Center has the capacity to measure a large number of classical biomarkers in sputum through our Sputum Core, including measures of cell counts, cytokines, and growth factors.
