Special Issue Information

Dear Colleagues,

Induced pluripotent stem cells (iPSCs) represent a new disease model and drug discovery tool, challenging the current limitations of animal models. Patient-specific iPSCs provide unlimited access to disease-relevant cells that are difficult to harvest, such as brain neurons and cardiomyocytes. Phenotypes associated with various diseases can be monitored and tested by using diverse cell types differentiated from iPSCs in culture. Monolayer 2D iPSC-derived cultures are convenient for the high-throughput screening of new drugs, some of which are being tested in clinical trials; however, 3D organoid models better reflect the cell–matrix interaction found in tissues and organs in vivo, such as the brain, heart, liver, kidney, gut, and lung. For example, midbrain organoids can model the key features of Parkinson’s disease. Moreover, the emergent gene editing fields provide the capacity to introduce or correct disease mutations in iPSCs to assess their contributions. Editing disease mutations in iPSCs to generate isogenic controls can shed light onto the causal relationship between genotypes and phenotypes; therefore, iPSCs have emerged as a wonderful model to facilitate new drug discovery and drug repositioning in human health.

This Special Issue will include recent advances in iPSC-based models of various diseases, in which gene editing is leveraged to highlight the impact of risk mutations.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The NLRP3 inflammasome plays a crucial role in the inflammatory response, reacting to pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). This response is essential for combating infections and restoring tissue homeostasis. However, chronic activation can lead to detrimental effects, particularly in [...] Read more.
The NLRP3 inflammasome plays a crucial role in the inflammatory response, reacting to pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). This response is essential for combating infections and restoring tissue homeostasis. However, chronic activation can lead to detrimental effects, particularly in neuropsychiatric and neurodegenerative diseases. Our study seeks to provide a method to effectively measure the NLRP3 inflammasome’s activation within cerebral organoids (COs), providing insights into the underlying pathophysiology of these conditions and enabling future studies to investigate the development of targeted therapies.
