Patent number: 12186333Abstract: RNA encoding an immunogen is co-delivered to non-immune cells as the site of delivery and also to immune cells which infiltrate the site of delivery. The responses of these two cell types to the same delivered RNA lead to two different effects, which interact to produce a strong immune response against the immunogen. The non-immune cells translate the RNA and express the immunogen. Infiltrating immune cells respond to the RNA by expressing type I interferons and pro-inflammatory cytokines which produce a local adjuvant effect which acts on the immunogen-expressing non-immune cells to upregulate major histocompatibility complex expression, thereby increasing presentation of the translated protein to T cells. The effects on the immune and non-immune cells can be achieved by a single delivery of a single RNA e.g., by a single injection.Type: GrantFiled: June 13, 2023Date of Patent: January 7, 2025Assignee: GlaxoSmithKline Biologicals SAInventors: Andrew Geall, Katrin Ramsauer, Gillis Otten, Christian Walter Mandl
