Autoimmune Disorders01:29

Autoimmune Disorders

1.3K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Tumor Immunotherapy01:27

Tumor Immunotherapy

1.6K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

366
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Cytotoxic T Cells-mediated Immune Response

6.3K
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...

  • To review recent advances in nanotechnology-based approaches for antigen-specific immune tolerance.
  • To highlight strategies for developing safer and more effective immunotherapies.

Main Methods:

  • Utilizing nanocarriers for targeted delivery of disease-relevant antigens to antigen-presenting cells.
  • Developing nanoparticle-based artificial antigen-presenting cells to directly target T cells.
  • Incorporating immunoregulatory agents within nanoparticles to modulate antigen-presenting pathways.

Main Results:

  • Nanoparticle-based strategies demonstrate potential for antigen-specific immune modulation.
  • Targeted delivery enhances preferential uptake by antigen-presenting cells, improving specificity.
  • These approaches offer a promising alternative to systemic immune suppression.

Conclusions:

  • Nanotechnology-based antigen-specific therapies represent a significant advancement in immunotherapy.
  • These novel strategies hold promise for achieving long-term disease remission with reduced off-target effects.
