The invention provides methods of treating inflammation in a specific organ or tissue of an individual. The method involves determining whether the individual has previously been infected with at least one pathogen that is pathogenic in the specific organ or tissue; and administering to the individual an anti-inflammatory composition comprising antigenic determinants, the antigenic determinants selected or formulated so that together they are specific for the at least one pathogen. The pathogen may be an endogenous or exogenous pathogen, and may further be a bacterial pathogen, a viral pathogen, a fungal pathogen, a protozoan pathogen, or a helminth pathogen.
Therapeutic modalities are provided involving the use of specific repertoirs of PRR ligands to ameliorate immune dysregulation in a perioperative period. In effect, innate immune system signaling is provoked in the perioperative period so as to facilitate a targeted immune response following surgery. Subjects may accordingly be treated with immunogenic formulations tailored to a specific target tissue to treat a subject during the perioperative period surrounding surgery to remove a solid tumor, where the target tissue is the site of the tumor or a characteristic site of metastasis for the cancer.
