1. A method of stimulating production of antimicrobial peptides in mammalian cells; the method comprises: a) contacting said cells in vitro with an effective amount of one or more compounds having one or more trihydroxybenzoate groups; andb) assessing a level of stimulation of the production of antimicrobial peptides; wherein, compared to a control, an increased stimulation of the production of antimicrobial peptides occurs. 2. The method of claim 1, wherein said antimicrobial peptides are LL-37, hBD2, hBD3, Ghrelin, Lysozyme or a combination thereof. 3. The method of claim 1, wherein the compounds having one or more trihydroxybenzoate groups are selected from 3,4,5-trihydroxybenzoic acid, 2,3,4-trihydroxybenzoic acid, C1-4-alkyl 3,4,5-trihydroxybenzoate, 2,3,4-trihydroxybenzoate, epigallocatechin gallate (EGCG), and mixtures thereof, in free or salt form. 4. The method of claim 2, wherein assessing a level of stimulation of the production of antimicrobial peptides comprises the steps of: a. contacting a sample with an antibody that binds to LL-37, hBD2, hBD3, Ghrelin, Lysozyme or a combination thereof sufficient to allow formation of a complex between a component of the sample and the antibody, to thereby form an antigen-antibody complex; andb. assessing the presence, absence, or amount of the antigen-antibody complex. 5. The method of claim 4, further comprising comparing the amount of the antigen-antibody complex to that of a control. 6. The method of claim 4, wherein said antibody is detectably labeled. 7. The method of claim 4, wherein the method further includes contacting the sample with a second antibody specific to LL-37, hBD2, hBD3, Ghrelin, Lysozyme or a combination thereof, or to said antigen-antibody complex. 8. The method of claim 4, wherein the anti-microbial peptide or the antibody is bound to a solid support. 9. A method of stimulating production of antimicrobial peptides in mammalian cells; the method comprises: a) contacting said cells in vitro with an effective amount of one or more compounds, wherein each of the one or more compounds has one trihydroxybenzoate group or two trihydroxybenzoate groups; andb) assessing a level of stimulation of the production of antimicrobial peptides; wherein, compared to a control, an increased stimulation of the production of antimicrobial peptides occurs. 10. The method of claim 9, wherein said antimicrobial peptides are LL-37, hBD2, hBD3. Ghrelin, Lysozyme or a combination thereof. 11. The method of claim 10, wherein assessing a level of stimulation of the production of antimicrobial peptides comprises the steps of: c. contacting a sample with an antibody that binds LL-37, hBD2, hBD3, Ghrelin, Lysozyme or a combination thereof sufficient to allow formation of a complex between a component of the sample and the antibody, to thereby form an antigen-antibody complex; andd. assessing the presence, absence, or amount of the antigen-antibody complex. 12. The method of claim 11, further comprising comparing the amount of the antigen-antibody complex to that of a control. 13. The method of claim 11, wherein said antibody is detectably labeled. 14. The method of claim 11, wherein the method further includes contacting the sample with a second antibody specific to LL-37, hBD2, hBD3, Ghrelin, Lysozyme or a combination thereof, or to said antigen-antibody complex. 15. The method of claim 11, wherein the anti-microbial peptide or the antibody is bound to a solid support.
