Inflammatory Response01:28

Inflammatory Response

12.1K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Inflammatory Response I: Vascular and Cellular

13.1K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

3.3K
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

4.1K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized...

Necrosis01:16

Necrosis

5.0K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Area of Science:

  • Immunology
  • Cell Biology
  • Pathology

Background:

  • Programmed cell death involves cells actively participating in their own destruction.
  • Programmed cell death is categorized into pro-inflammatory and non-inflammatory pathways.
  • Pyroptosis is a pro-inflammatory programmed cell death pathway characterized by cytokine release.

Purpose of the Study:

  • To review the inflammatory response triggered by pyroptosis.
  • To examine the resulting tissue damage in selected organs due to pyroptosis.

Main Methods:

  • Literature review focusing on pyroptosis and inflammation.
  • Analysis of studies detailing pyroptosis-induced tissue damage.

Main Results:

  • Pyroptosis releases cytokines, initiating inflammatory cascades.
  • Pyroptosis acts as a double-edged sword, with both beneficial and detrimental roles in disease.
  • Inflammatory responses from pyroptosis can lead to tissue damage and host mortality.

Conclusions:

  • Pyroptosis-induced inflammation significantly contributes to tissue damage in various conditions.
  • Understanding pyroptosis is crucial for managing inflammatory disorders.
