Stimulation of dendritic cells enhances immune response after photodynamic therapy
Photodynamic therapy (PDT) involves the administration of photosensitizers followed by illumination of the primary tumor with red light producing reactive oxygen species that cause vascular shutdown and tumor cell necrosis and apoptosis. Anti-tumor immunity is stimulated after PDT due to the acute inflammatory response, priming of the immune system to recognize tumor-associated antigens (TAA). ...
متن کاملPhotodynamic Therapy of Tumors Can Lead to Development of Systemic Antigen-Specific Immune Response
BACKGROUND The mechanism by which the immune system can effectively recognize and destroy tumors is dependent on recognition of tumor antigens. The molecular identity of a number of these antigens has recently been identified and several immunotherapies have explored them as targets. Photodynamic therapy (PDT) is an anti-cancer modality that uses a non-toxic photosensitizer and visible light to...
متن کاملAntigen specific and nonspecific modulation of the immune response by aminolevulinic acid based photodynamic therapy.
Photosensitizers used normally in treating cancers have considerable potential for treatment of other diseases. One such photosensitizer is the endogenously synthesized photosensitizer protoporphyrin IX (PpIX). To better understand how protoporphyrin might be used in transplantation or in treating autoimmune diseases, information must be obtained on how the photosensitizer affects all immune ce...
متن کاملPhotodynamic therapy-mediated immune response against subcutaneous mouse tumors.
The curative ability of photodynamic therapy (PDT) is severely compromised if treated tumors are growing in immunodeficient hosts. Reconstitution of severe combined immunodeficient (scid) mice with splenocytes from naive immunologically intact BALB/c mice did not improve the response to Photofrin-based PDT of EMT6 tumors growing in these animals. In contrast, adoptive transfer of BALB/c splenoc...
متن کاملMreg Activity in Tumor Response to Photodynamic Therapy and Photodynamic Therapy-Generated Cancer Vaccines
Myeloid regulatory cells (Mregs) are, together with regulatory T cells (Tregs), a dominant effector population responsible for restriction of the duration and strength of antitumor immune response. Photodynamic therapy (PDT) and cancer vaccines generated by PDT are modalities whose effectiveness in tumor destruction is closely dependent on the associated antitumor immune response. The present s...
