Summary
Caspase activation is heightened in periodontitis, a gum disease caused by bacteria. This study reveals caspases contribute to tissue damage by triggering cell death pathways, offering insights into periodontitis pathology.
Area of Science:
- Cell Biology
- Oral Microbiology
- Immunology
Background:
- Periodontitis is a prevalent infectious oral disease.
- It involves gram-negative bacteria and periodontal tissue destruction.
- Caspases are key intracellular proteases mediating apoptosis (programmed cell death).
Purpose of the Study:
- To investigate the role of caspases in periodontitis-associated tissue injury.
- To determine if periodontopathic bacteria influence caspase activation.
- To explore the mechanisms of host-mediated cytotoxicity in periodontitis.
Main Methods:
- Analysis of caspase-3 and caspase-7 activation in gingival tissue from periodontitis patients.
- In vitro experiments with periodontopathic bacteria.
- Investigation of the CD95 death receptor pathway.
Main Results:
- Caspase-3 and caspase-7 activation is significantly increased in periodontitis gingival tissue.
- Periodontopathic bacteria directly suppress bacterial growth in vitro.
- Bacteria can induce host-mediated cytotoxicity via the CD95 death receptor pathway.
Conclusions:
- Caspase activation is a significant feature of tissue injury in periodontitis.
- These findings highlight the involvement of apoptosis in periodontitis pathogenesis.
- Understanding these pathways may inform future therapeutic strategies for periodontitis.

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.
01:24Caspases
Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside cells.
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...
01:26Acute Inflammation II: Cellular Phase
The cellular phase of acute inflammation is a tightly orchestrated sequence of events that recruits leukocytes, primarily neutrophils, to sites of tissue injury or infection. Following the initial vascular changes, this phase ensures effective immune cell migration, activation, and function at the affected site to eliminate pathogens and initiate tissue repair.Leukocyte Recruitment CascadeLeukocyte recruitment happens in four steps: margination, adhesion, transmigration, and chemotaxis. Reduced...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
