Insights

MicroRNAs (miRNAs) regulate neuronal functions and their dysregulation is linked to neurological diseases. Manipulating miRNAs in various models shows therapeutic potential for conditions like Alzheimer's and autism.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are non-coding RNAs with crucial regulatory roles in neuronal functions across species.
  • Aberrant miRNA expression is implicated in the pathogenesis of neuropsychiatric and neurodegenerative disorders, including schizophrenia, Alzheimer's disease, and autism.

Purpose of the Study:

  • To review the regulatory roles of miRNAs in neuronal functions.
  • To explore the potential of miRNAs as therapeutic targets for neurological diseases.

Main Methods:

  • Review of existing literature on miRNA function and neurological disorders.
  • Analysis of studies involving miRNA manipulation in various model systems (Drosophila, rodents, primates).

Main Results:

  • miRNAs are conserved regulators of neuronal functions.
  • Specific miRNA dysregulation is associated with major neurological diseases.
  • Experimental manipulation of miRNAs can modify disease-related phenotypes in model organisms.

Conclusions:

  • miRNAs represent a promising class of therapeutic targets for neurological diseases.
  • Diverse biological systems, from invertebrates to primates, can be utilized to translate miRNA research into clinical applications.

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
