Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of peptide antigen via MHC class II.

Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of peptide antigen via MHC class II.

The internalization of bacteria, immune complexes and other particulate matter or of an apoptotic cell by phagocytosis, including the membrane and cytoskeletal processes required, which involves one of three mechanisms: zippering of pseudopods around a target via repeated receptor-ligand interactions, sinking of the target directly into plasma membrane of the phagocytosing cell, or induced uptake via an enhanced membrane ruffling of the phagocytosing cell similar to macropinocytosis.

An immune response mediated through a body fluid.

A series of molecular signals initiated by the binding of a lipopolysaccharide (LPS) to a receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription. Lipopolysaccharides are major components of the outer membrane of Gram-negative bacteria, making them prime targets for recognition by the immune system.

The series of events in which a lipopolysaccharide stimulus is received by a cell and converted into a molecular signal. Lipopolysaccharide is a major component of the cell wall of gram-negative bacteria.

The series of events in which a peptidoglycan stimulus is received by a cell and converted into a molecular signal. Peptidoglycan is a bacterial cell wall macromolecule.

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

Any process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine.

Any process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine.

Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.

Any process that activates or increases the frequency, rate or extent of calcium-mediated signaling.

Any process that activates or increases the frequency, rate or extent of calcium-mediated signaling.

Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.

Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.

The series of events in which a lipoteichoic acid stimulus is received by a cell and converted into a molecular signal; lipoteichoic acid is a major component of the cell wall of gram-positive bacteria and typically consists of a chain of glycerol-phosphate repeating units linked to a glycolipid anchor.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipoteichoic acid stimulus; lipoteichoic acid is a major component of the cell wall of gram-positive bacteria and typically consists of a chain of glycerol-phosphate repeating units linked to a glycolipid anchor.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a peptidoglycan stimulus. Peptidoglycan is a bacterial cell wall macromolecule.

The process in which a precursor cell type acquires the specialized features of a dendritic cell. A dendritic cell is a leukocyte of dendritic lineage specialized in the uptake, processing, and transport of antigens to lymph nodes for the purpose of stimulating an immune response via T cell activation.

Any process that activates or increases the frequency, rate or extent of protein localization to plasma membrane.

Any process that activates or increases the frequency, rate or extent of protein localization to plasma membrane.

Any process that activates or increases the frequency, rate or extent of C-C chemokine receptor CCR7 signaling pathway.

Any process that activates or increases the frequency, rate or extent of C-C chemokine receptor CCR7 signaling pathway.

Any process that activates or increases the frequency, rate or extent of signaling via the CD40 signaling pathway.

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
