(?- or -shaped response pattern) toward the levels seen under baseline conditions, suggesting a peak response at 4 hr(or at least earlier than 24 hr). 3) In a third set (n = 5), levels of some proteins at 24 hr were continuing to either increase or decrease from levels seen at 4 hr, suggesting slower and/or more sustained responses to infection. With respect to all identified proteins, the ratio

Require further optimization. In addition to viral vectors, recombinant bacterial carriersRequire further optimization. In addition to viral vectors, recombinant bacterial carriers, derived from lactic acid bacteria, Salmonella and L. monocytogenes strains, have been used extensively as delivery systems being able to stimulate both systemic [29,30] and mucosal immune responses .GENE DELIVERY
