Toxic Reactions: Overview

1.7K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Allergic Drug Reactions

1.3K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Cytotoxic T Cells-mediated Immune Response

6.4K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Immunological Memory01:23

Immunological Memory

14.7K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.8K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

    Summary
    This summary is machine-generated.

    Chemicals can cause toxicity by damaging tissues through immune system mechanisms. This study explores how chemicals, like alkyl tins, can alter immune cell function, potentially leading to toxic effects and hypersensitivity reactions.

    • Review of existing literature on chemical toxicity and immunomodulation.
    • Exploration of the mechanism of hypersensitivity reactions.
    • Analysis of factors governing antigenicity in small molecular weight compounds.

    Main Results:

    • Chemicals can induce perturbations in immunological competence, a debated toxicological hazard.
    • Hypersensitivity, a form of tissue damage, is linked to a substance acting as an antigen.
    • Experimental work with practolol shows antibodies reacting with its metabolic products.

    Conclusions:
