Cell-mediated immunity. T cells play a key role in cell-mediated immunity by directly attacking infected cells or coordinating the immune response.
Cell-mediated immunity decreases at puberty due to hormonal changes that can influence the development and function of immune cells, such as T cells. During puberty, there is a shift in the balance between pro-inflammatory and anti-inflammatory responses, which can affect immune regulation and responsiveness. Additionally, hormonal changes can impact the production of cytokines and other immune mediators involved in cell-mediated immunity.
A defect in the cell-mediated immune system response was identified with regard to Hepatitis B (with many articles written about this in 2008-2009). HIV-AIDS is another disease with a defect in cell-mediated immune response, as well. There are other immunodeficiency diseases involving this kind of defect, too. immunological deficiency syndroms
This process is called cell-mediated immunity. T cells, specifically cytotoxic T cells, recognize and destroy cells that are infected with a pathogen or abnormal cells, such as cancer cells. This immune response is crucial for clearing infections and providing immunity against future exposures to the same antigen.
Cell-mediated responses primarily target intracellular pathogens, such as viruses and some bacteria, as well as cancer cells and transplanted tissues. This immune response involves T cells, particularly cytotoxic T lymphocytes (CTLs), which recognize and destroy infected or abnormal cells. Additionally, helper T cells assist in activating other immune cells to enhance the overall immune response. Overall, cell-mediated immunity is crucial for eliminating pathogens that evade antibody-mediated responses.

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.

This immune response is crucial for clearing infections and providing immunity against future exposures to the same antigen.
The cell-mediated immune response is able to target and destroy infected cells directly, providing a more rapid response to intracellular pathogens. It also plays a key role in immunological memory, allowing the immune system to remember and quickly respond to future encounters with the same pathogen. Additionally, cell-mediated immunity can provide long-lasting protection against certain infections.

AIDS- acquired immune deficiency syndrome
T lymphocytes (T cells) are the cell type that interacts with both humoral and cell-mediated immune pathways. They help orchestrate immune responses by recognizing antigens presented by antigen-presenting cells and signaling other immune cells to either produce antibodies (in the case of B cells) or kill infected cells directly.
Non-living things such as toxins, chemicals, and drugs do not respond to cell-mediated immunity since they do not have cells or antigens that can be recognized and targeted by the immune system's T cells.
