Study Notes
Gut-Brain Axis
- The gut-brain axis highlights the connection between the gut microbiome and brain function.
- The microbiome influences both physiological and pathological processes in the brain.
- Alterations in the microbiome can lead to various diseases.
Importance of Cell Biology
- Understanding cell biology is crucial to comprehend how human bodies function.
- Human body comprises approximately 37 trillion cells, collaborating rather than competing.
Genetic Diseases
- There are roughly 24,000 genes in the human genome, fewer than previously estimated.
- Alternative splicing allows one gene to produce multiple proteins.
- Genetic diseases, such as Cerebral Cavernous Malformation (CCM), arise from gene mutations.
Cerebral Cavernous Malformation (CCM)
- CCM is a cerebrovascular disease affecting brain capillaries, leading to serious clinical symptoms.
- Symptoms may include seizures, neurological deficits, and intracerebral hemorrhages (ICH).
- The capillaries in CCM are enlarged, leaky, and vulnerable to hemorrhage.
Diagnostics and Clinical Symptoms
- MRI is the primary diagnostic tool for CCM, effective since the 1980s.
- Lesions are categorized by size and can vary from one to multiple (up to 700).
- Symptoms can range from headaches to severe neurological deficits, depending on lesion location.
Treatment Approaches
- Current treatment options include neurosurgery to remove cavernous malformations.
- Pharmacological treatments are still under development, with clinical trials ongoing.
Pathogenesis of CCM
- CCM can develop dynamically, and its occurrence may be congenital or acquired in adulthood.
- Key questions in understanding CCM are its formation, localization, and timing during an individual's life.
Genetic Factors
- Three genes associated with CCM have been identified: CCM1, CCM2, and CCM3.
- CCM1 (KRIT1) is the most commonly mutated gene linked to this condition.
- Genetic mapping has shown the location of these genes on chromosomes 3 and 7.
Funding and Research
- A significant portion of funding for research supports studies on genetic and molecular bases of diseases.
- Promising therapeutic approaches are emerging as knowledge of these bases increases.
