IgG and IgM can fix complement by activating the C3 protein at the end of the complement cascade allowing ADCC (antibody dependent cell- mediated cytoxicity) to occur. I have never heard of an IgC antibody. In humans there are only 5 classes of antibodies: IgM, IgG, IgA. IgD & IgE.
This statement is not accurate. Pathogens can provoke both cell-mediated and antibody-mediated responses at the same time. The type of immune response generated depends on the specific characteristics of the pathogen and the immune system of the host.

T cell mediated immunity and B cell immunity (Antibody secretion.
Hypersensitivity reactions are classified into four categories: Type I (immediate hypersensitivity), which involves IgE-mediated responses leading to allergic reactions; Type II (antibody-mediated cytotoxicity), where antibodies target specific cells; Type III (immune complex-mediated), characterized by the formation of antibody-antigen complexes that trigger inflammation; and Type IV (delayed-type hypersensitivity), which is mediated by T cells and manifests hours to days after exposure to the allergen. Each type involves distinct immune mechanisms and clinical manifestations.

Membrane cofactor protein (MCP) acts as a cofactor for Factor I, which degrades C3b and C4b proteins, thus preventing the amplification of complement activation. By accelerating the decay of C3 convertases, MCP helps regulate the complement system and protect host cells from excessive complement-mediated damage.
Lymphocyteononuclear white blood cell that is responsible for humoral (antibody mediated) and cell mediated immunity.Lymphs Electronic is a lab test to measure the amount of this kind of white blood cell. The results are reported in percentages.There is also a Lymphs Absolute test and results are reported in K/uL
Antibody-mediated response, also known as humoral immunity, is a crucial aspect of the adaptive immune system where B cells produce antibodies in response to specific antigens. These antibodies bind to pathogens such as bacteria and viruses, neutralizing them or marking them for destruction by other immune cells. This response is essential for providing long-lasting immunity and is the basis for the effectiveness of many vaccines. It plays a vital role in protecting the body against infections and diseases.
Epidermal cells that aid in the immune response include melanocytes.
