The process by which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC class Ib protein complex. Class Ib here refers to non-classical class I molecules, such as those of the CD1 or HLA-E gene families. The process by which an antigen-presenting cell expresses peptide antigen in association with an MHC class Ib protein complex on its cell surface. The peptide antigen may originate from an endogenous or exogenous protein. Class Ib here refers to non-classical class I molecules, such as those of the HLA-E family. The process by which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC protein complex. The process by which an antigen-presenting cell expresses lipid antigen in association with an MHC class Ib protein complex on its cell surface, including lipid extraction, degradation, and transport steps for the lipid antigen both prior to and following assembly with the MHC protein complex. The lipid antigen may originate from an endogenous or exogenous source of lipid. Class Ib here refers to non-classical class I molecules, such as those of the CD1 family. Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of antigen via MHC class Ib. Any process that modulates the frequency, rate, or extent of antigen processing and presentation of antigen via MHC class Ib. Any process that stops, prevents, or reduces the frequency, rate, or extent of antigen processing and presentation of antigen via MHC class Ib. Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
