The two types of specific immune responses are humoral immunity, mediated by B cells producing antibodies to neutralize extracellular pathogens and their products, and cell-mediated immunity, involving T cells that directly kill infected cells or help coordinate the immune response

sabine and jouri

2025-10-08 09:52:44 UTC

The two types of specific immune responses are cell-mediated immunity and humoral immunity (antibody-mediated immunity). Cell-mediated immunity uses T-lymphocytes to directly destroy infected cells, while humoral immunity uses B-lymphocytes to produce antibodies that neutralize and mark pathogens for destruction

Hussein t

2025-10-08 09:52:59 UTC

The two types of specific immune responses, or adaptive immunity, are humoral immunity and cell-mediated immunity. Humoral immunity is mediated by antibodies produced by plasma cells (effector B cells), targeting pathogens and toxins in bodily fluids. Cell-mediated immunity is carried out by T lymphocytes, including helper T cells that coordinate immune responses and cytotoxic T cells that directly kill infected or cancerous cells.

An antibody is a protein produced by B cells that specifically recognizes and binds to antigens, while an antigen is any molecule that can trigger an immune response; B cells mediate immunity primarily by producing antibodies that neutralize or mark antigens for destruction.

1)a Y-shaped protein produced by the immune system to identify and neutralize foreign substances called antigens, such as bacteria and viruses

2)a substance that can trigger an immune response from the body, often by causing the production of antibodies to fight it

3)produce antibodies that neutralize pathogens and foreign substances

1-An antibody, or immunoglobulin, is a Y-shaped protein produced by the immune system to identify and neutralize foreign substances called antigens, such as bacteria and viruses.

2-An antigen is a substance that can trigger an immune response in the body, often by causing the production of antibodies.

they will start their multiplication based on a specific region

rush towards the cancer cells

adhere to the membrane

perforate them leading to destruction

-macrophage can’t kill pathogen

-macrophage presents a fragment of the antigen to the t cells(killer cells)

-Activated T cells will multiply

-T cells will rush towards the antigen

-T cells adhere to the membrane of the antigen

- T cells destroy the pathogen
