Summary
This study found that apoptosis, or programmed cell death, is present in aortic dissection cases but not in healthy controls. Increased apoptosis, particularly within the first month, suggests its role in the development of aortic dissection.
Area of Science:
- Cardiovascular Biology
- Cellular Pathology
Context:
- Aortic dissection is a life-threatening condition involving a tear in the aorta's inner layer.
- The underlying mechanisms contributing to aortic dissection remain incompletely understood.
- Investigating cellular processes like apoptosis may reveal key factors in disease pathogenesis.
Purpose:
- To investigate the role of apoptosis in the occurrence of Stanford type A aortic dissection.
- To correlate the presence and distribution of apoptotic cells with clinical timelines and inflammatory markers.
Summary:
- A TUNEL assay revealed apoptotic cells in all 11 Stanford type A aortic dissection patients, but none in 4 autopsy controls.
- Apoptotic cells were significantly more abundant on the false lumen surface within 1 month post-dissection compared to later cases.
- Immunohistological staining showed increased macrophages (CD 68) and human matrix metalloproteinase-9 (h-MMP-9) correlating with apoptosis.
Impact:
- These findings suggest that apoptosis is a contributing factor in the development of aortic dissection.
- Understanding apoptosis's role may open new avenues for therapeutic interventions targeting aortic dissection.

01:30Apoptosis
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
01:17The Extrinsic Apoptotic Pathway
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
