Step 1: A macrophage engulfs the pathogen. Step 2: The macrophage then digests the bacterium and presents the pathogen's antigens. Step 3: A T helper cell binds to the macrophage and becomes an activated T helper cell. Step 4: The activated T helper cell binds to a B cell in order to activate the B cell.

How are antibodies produced?from technologynetworks.com
Each B cell produces its own set of antibodies with unique antigen-specific binding sites. Initially, naïve B cells produce antibodies that remain bound to the cellular surface so that their exposed antigen-binding sites can detect potential pathogens, toxins and foreign material. This surface-bound form of an antibody is known as an immunoglobulin.
Why do antibodies work?from en.wikipedia.org
Each antibody recognizes a specific antigen unique to its target. By binding their specific antigens, antibodies can cause agglutination and precipitation of antibody-antigen products , prime for phagocytosis by macrophages and other cells, block viral receptors, and stimulate other immune responses, such as the complement pathway.
What is the difference between a cell-mediated immune response and a phagocytosis response?from biologydictionary.net
Instead, they use APC-activated T helper cells to secrete cytokines and these attract white blood cells. White blood cells (the cell-mediated part of this response) digest foreign particles via phagocytosis. Phagocytes are non-specific – they attack and digest any foreign particle they come across.

These T-memory cells persist for the remainder of a person’s life.
What is humoral immunity?from byjus.com
Humoral Immunity. Humoral immunity is mediated by antibodies. It shows a quick response against pathogens. It is the major defence mechanism against extracellular microbes trying to invade the host systems. The antibodies produced by the B-cells bind to the antigens and neutralize the microbes.

What is the function of T4-helper lymphocytes?from bio.libretexts.org
Cytokines produced by effector T4-helper lymphocytes enable the now activated T4- and T8-lymphocyte to rapidly proliferate to produce large clones of thousands of identical T4- and T8-lymphocytes. In this way, even though only a few T-lymphocytes in the body may have TCR molecule able to fit a particular epitope, eventually many thousands of cells are produced with the right specificity. This is referred to as clonal expansion. These cells then differentiate into effector T4-lymphocytes and cytotoxic T-lymphocytes or CTLs.

How does humoral immunity work?from biologydictionary.net
Humoral immunity is provided by several immune cell types and occurs in specific stages. Older vaccines trigger the humoral immune response by introducing weakened or dead pathogens; newer vaccine developments use templates or mRNA sequences to set our humoral immunity response into motion. These newer vaccines are making headlines thanks to the COVID-19 pandemic.
What are the functions of B cells?from biologydictionary.net
B cells have three functions: as antigen-presenting cells (see above), to secrete chemical messaging molecules called cytokines (the colored dots), and to produced antibodies as part of the humoral immune response. When still in the bone marrow, B cells develop membrane receptors – B-cell receptors or BCRs.

How are helper T cells recognized?from biologydictionary.net
Helper T cells are themselves recognized by MHC II via a CD surface protein. T cells can also differentiate into memory T cells that, upon a second infection involving the same antigen, produce both cytotoxic and helper T cells.
Humoral Immunity
- When foreign material - antigens- is recognized in the body, the body responds with an antibody-mediated reaction. Extracellular intruders, such as bacteria, are commonly found in this foreign material. B cell lymphocytes, a type of immune cell that makes antibodies after detecting a specific antigen, are principally responsible for this method. Ly...
Cell-Mediated Immunity
- Cell-mediated immunity, unlike humoral immunity, does not rely on antibodies to perform adaptive immunological activities. Mature T cells, macrophages, and the production of cytokines in response to an antigen are the main drivers of cell-mediated immunity. To recognize intracellular target antigens, T cells that participate in cell-mediated immunity rely on antigen-presenting cell…
Humoral vs Cell-Mediated
- B cells activate humoral immunity, whereas T cells activate cell-mediated immunity. The major difference between humoral and cell-mediated immunity is that humoral immunity produces antigen-specific antibodies, whereas cell-mediated immunity does not. T lymphocytes, on the other hand, kill infected cells by triggering apoptosis. Humoral immunity develops quickly, where…
Significance of Humoral and Cell-Mediated Immune Response
- T-cell responses, which are part of cell-mediated immunity, play a vital role in controlling viral infections. T-cells do this through developing effector activities such as the generation of chemokines and cytokines, which can have direct and indirect antiviral effects, as well as assisting in the overall immune response regulation. Certain effector T-cells can kill virus-infected cells vi…
