As part of the innate immune response, the NLRP3 inflammasome detects a wide range of danger signals such as pathogens, tissue damages, cellular stress. The priming and activation of NLRP3 lead to the formation of an oligomeric intracellular complex and to the recruitment and activation of caspase-1. Once activated, not only this inflammasome complex controls the processing and release of pro-inflammatory factors including IL-1β and IL-18, but also the inflammatory cell death pyroptosis mediated by gasdermin D pores. In this review, we describe the role of the NLRP3 inflammasome activation in viral infections with a particular interest on SARS-CoV-2 infection. In addition, we present therapies evaluated or under evaluation targeting the NLRP3 inflammasome pathway as COVID-19 treatment.</p>","PeriodicalId":519512,"journal":{"name":"Medecine sciences : M/S","volume":"38 6-7","pages":"545-552"},"PeriodicalIF":0.7,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40408643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mitochondria are key organelles that control several metabolic processes and represent the main source of energy in the form of ATP. Intracellular transport of mitochondria is essential for addressing these organelles to the right place at the right time according to energy requirement. Mitochondrial transport in cancer cells involves mitochondria-associated Miro/TRAK complexes that bind to motor proteins (kinesins, dyneins and myosins) to promote mitochondrial displacement along microtubules or actin filaments. This review focuses on the molecular players of intracellular mitochondrial transport along microtubules during cell migration and mitosis, and their deregulation in tissues from cancer patients. Intercellular mitochondrial transport upon cancer cell exposure to hypoxia or chemotherapy is also presented. This field of investigation opens new interesting perspectives in oncology, as targeting mitochondrial transport may represent an innovative strategy for treating cancer.</p>","PeriodicalId":519512,"journal":{"name":"Medecine sciences : M/S","volume":"38 6-7","pages":"585-593"},"PeriodicalIF":0.7,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40408871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is currently integrated into specific therapeutic schemes and therapeutic stratification, but the surgical procedure itself as well as its evaluation do not rely on tumor biology.

Overall, these studies provide a proof of principle that precision surgery, i.e. based on tumor biology, similarly to precision medicine, is applicable to head and neck cancers.","PeriodicalId":519512,"journal":{"name":"Medecine sciences : M/S","volume":"38 6-7","pages":"562-569"},"PeriodicalIF":0.7,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40409413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
