Innate Immunity - an overview ScienceDirect Topics

Immunogenicity is the ability of a foreign substance, such as an antigen, to provoke an immune response in the body of a human or other animal. It may be wanted or unwanted: • Wanted immunogenicity typically relates to vaccines, where the injection of an antigen (the vaccine) provokes an immune response against the pathogen, protecting the organism from future exposure. Immunogenicity is a central aspect of vaccine development. Web25 de fev. de 2024 · Innate immune response is usually activated by host immune system through detecting exogeneous motifs called pathogen-associated molecular patterns (PAMPs) via the pattern recognition receptors (PRRs) [ 17 ]. These receptors are particularly highly expressed in APCs, the major target cell population of mRNA cancer vaccines. high sierra coconut bunk bed
