Summary
Psoriasis involves immune cells and genetic factors like CARD14 mutations. The paracaspase MALT1 activates key pathways, driving disease progression through its protease and scaffold functions, offering therapeutic targets.
Area of Science:
- Immunodermatology
- Molecular biology
- Genetics
Background:
- Psoriasis is a common autoimmune skin disease involving T cells, keratinocytes, and dendritic cells.
- Genetic variations, including CARD14 mutations, are implicated in psoriasis development.
- Immune and cytokine receptor stimulation activates paracaspase MALT1.
Purpose of the Study:
- To review the role of MALT1-mediated signaling in psoriasis.
- To discuss the therapeutic implications of targeting MALT1 in psoriasis treatment.
Main Methods:
- Review of scientific literature on MALT1 signaling in psoriasis.
- Analysis of the molecular mechanisms of MALT1 in disease pathogenesis.
Main Results:
- MALT1 activation by CARD14 mutations and receptor stimulation.
- MALT1's dual role in psoriasis pathogenesis via protease and scaffold functions.
- MALT1 signaling influences transcription factors NF-κB and AP-1.
Conclusions:
- MALT1 plays a significant role in promoting psoriasis.
- Targeting MALT1-mediated signaling presents potential therapeutic strategies for psoriasis.

01:24Caspases
12.9K
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...

01:31The Intrinsic Apoptotic Pathway
7.2K
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...

01:07MAPK Signaling Cascades
6.7K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

01:22PI3K/mTOR/AKT Signaling Pathway
4.3K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

01:17The Extrinsic Apoptotic Pathway
6.9K
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...

01:20The JAK-STAT Signaling Pathway
9.8K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
