The ‘speck’-tacular oversight of the NLRP3-pyroptosis pathway on gastrointestinal inflammatory diseases and tumorigenesis J. Biomed. Sci. (IF 11.0) Pub Date : 2023-10-27 Valentina Arrè, Rosanna Scialpi, Matteo Centonze, Gianluigi Giannelli, Maria Principia Scavo, Roberto Negro
The NLRP3 inflammasome is an intracellular sensor and an essential component of the innate immune system involved in danger recognition. An important hallmark of inflammasome activation is the formation of a single supramolecular punctum, known as a speck, per cell, which is the site where the pro-inflammatory cytokines IL-1β and IL-18 are converted into their bioactive form. Speck also provides the

Crosstalk between mitochondrial biogenesis and mitophagy to maintain mitochondrial homeostasis J. Biomed. Sci. (IF 11.0) Pub Date : 2023-10-12 Lei Liu, Yanjun Li, Guo Chen, Quan Chen
Mitochondrial mass and quality are tightly regulated by two essential and opposing mechanisms, mitochondrial biogenesis (mitobiogenesis) and mitophagy, in response to cellular energy needs and other cellular and environmental cues. Great strides have been made to uncover key regulators of these complex processes. Emerging evidence has shown that there exists a tight coordination between mitophagy and

Extracellular release in the quality control of the mammalian mitochondria J. Biomed. Sci. (IF 11.0) Pub Date : 2023-10-08 Kuei-Hsiang Pan, Hung Chang, Wei Yuan Yang
Mammalian cells release a wealth of materials to their surroundings. Emerging data suggest these materials can even be mitochondria with perturbed morphology and aberrant function. These dysfunctional mitochondria are removed by migrating cells through membrane shedding. Neuronal cells, cardiomyocytes, and adipocytes send dysfunctional mitochondria into the extracellular space for nearby cells to degrade

Clinical trials of new drugs for Alzheimer disease: a 2020–2023 update J. Biomed. Sci. (IF 11.0) Pub Date : 2023-10-02 Li-Kai Huang, Yi-Chun Kuan, Ho-Wei Lin, Chaur-Jong Hu
Alzheimer's disease (AD) is the leading cause of dementia, presenting a significant unmet medical need worldwide. The pathogenesis of AD involves various pathophysiological events, including the accumulation of amyloid and tau, neuro-inflammation, and neuronal injury. Clinical trials focusing on new drugs for AD were documented in 2020, but subsequent developments have emerged since then. Notably,

Induced pluripotent stem cells: ex vivo models for human diseases due to mitochondrial DNA mutations J. Biomed. Sci. (IF 11.0) Pub Date : 2023-09-22 Chao Chen, Min-Xin Guan
Mitochondria are essential organelles for cellular metabolism and physiology in eukaryotic cells. Human mitochondria have their own genome (mtDNA), which is maternally inherited with 37 genes, encoding 13 polypeptides for oxidative phosphorylation, and 22 tRNAs and 2 rRNAs for translation. mtDNA mutations are associated with a wide spectrum of degenerative and neuromuscular diseases. However, the pathophysiology

Interaction of the AKT and β-catenin signalling pathways and the influence of photobiomodulation on cellular signalling proteins in diabetic wound healing J. Biomed. Sci. (IF 11.0) Pub Date : 2023-09-21 Sandy Winfield Jere, Heidi Abrahamse, Nicolette Nadene Houreld
The induction of a cells destiny is a tightly controlled process that is regulated through communication between the matrix and cell signalling proteins. Cell signalling activates distinctive subsections of target genes, and different signalling pathways may be used repeatedly in different settings. A range of different signalling pathways are activated during the wound healing process, and dysregulated
