Antigen

In immunology, an antigen is a molecule capable of inducing an immune response (to produce an antibody) in the host organism.

New!!: QS21 and Antigen · See more »

Cancer

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.

New!!: QS21 and Cancer · See more »

Cell-mediated immunity

Cell-mediated immunity is an immune response that does not involve antibodies, but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

Chemical compound

A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds.

HIV

The human immunodeficiency virus (HIV) is a lentivirus (a subgroup of retrovirus) that causes HIV infection and over time acquired immunodeficiency syndrome (AIDS).

Humoral immunity

Humoral immunity or humoural immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides.

New!!: QS21 and Humoral immunity · See more »

Immune system

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease.

New!!: QS21 and Immune system · See more »

Immunity (medical)

In biology, immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or other unwanted biological invasion, while having adequate tolerance to avoid allergy, and autoimmune diseases.

New!!: QS21 and Immunity (medical) · See more »

Immunologic adjuvant

In immunology, an adjuvant is a component that potentiates the immune responses to an antigen and/or modulates it towards the desired immune responses.

New!!: QS21 and Immunologic adjuvant · See more »

Malaria

Malaria is a mosquito-borne infectious disease affecting humans and other animals caused by parasitic protozoans (a group of single-celled microorganisms) belonging to the Plasmodium type.

Quillaia

Quillaia is the milled inner bark or small stems and branches of the soapbark (''Quillaja saponaria'', Molina).

Quillaja saponaria

Quillaja saponaria, the soap bark tree or soapbark, is an evergreen tree in the family Quillajaceae, native to warm temperate central Chile.
