Peptides that specifically bind erythrocytes are described. These are provided as peptidic ligands having sequences that specifically bind, or as antibodies or fragments thereof that provide specific binding, to erythrocytes. The peptides may be prepared as molecular fusions with therapeutic agents, tolerizing antigens, or targeting peptides. Immunotolerance may be created by use of the fusions and choice of an antigen on a substance for which tolerance is desired. Fusions with targeting peptides direct the fusions to the target, for instance a tumor, where the erythrocyte-binding ligands reduce or entirely eliminate blood flow to the tumor by recruiting erythrocytes to the target.

The invention relates to C. acnes carrying DNA vectors with a C. acnes phage packaging signal and a gene of interest. The invention encompasses a C. acnes producer cell carrying DNA vectors, with a C. acnes phage packaging signal and a gene of interest, for the production of phage-derived particles that can robustly transduce C. acnes receiver cell allowing transgene expression. The invention encompasses C. acnes phage-derived particles carrying these vectors, C. acnes containing these vectors or modified by transduction of these phage-derived particles, and methods of using these phage-derived particles.

The present invention relates to pharmaceutical compositions containing lipid-bacteriophage conjugates, wherein the bacteriophage:lipid ratio is in the range of 3:1 to 100:1 and wherein the lipid is an immunologically active lipid and the bacteriophage is a filamentous bacteriophage, and uses thereof. Preferably, the bacteriophage is engineered to stimulate an immune response and/or bind to a target cell.
