Resumen
Los elovanoides, derivados del ácido docosahexaenoico (DHA), protegen la integridad del sistema nervioso activando sistemas antioxidantes y previniendo el daño celular. La ingesta dietética de DHA apoya la producción de elovanoides para la neuroprotección contra enfermedades relacionadas con la edad.
Área de la Ciencia:
- Bioquímica de mediadores lipídicos; Mecanismos de neuroprotección; Sistemas antioxidantes celulares
Sus antecedentes:
- Los elovanoides son mediadores lipídicos homeostáticos derivados de ácidos grasos poliinsaturados n-3 de cadena muy larga.; Estos ácidos grasos se originan a partir del ácido docosahexaenoico (DHA).
Objetivo del estudio:
- Revisar las últimas investigaciones sobre elovanoides.; Resumir su papel en la homeostasis celular y la neuroprotección.
Principales métodos:
- Revisión de literatura de estudios recientes sobre elovanoides.; Análisis de la función de los elovanoides en modelos celulares y estados de enfermedad.
Principales resultados:
- Los elovanoides modulan la tioredoxina reductasa 1, mejorando el sistema antioxidante del glutatión.; Previenen la senescencia y la inflamación inducidas por el amiloide beta.; La reducción de la conversión de DHA en precursores de elovanoides ocurre en la degeneración macular asociada a la edad.
Conclusiones:
- Los elovanoides actúan como guardianes moleculares de la integridad del sistema nervioso.; Proporcionan una primera línea de defensa crucial contra el daño de las células neuronales.; La ingesta dietética de DHA es vital para la neuroprotección mediada por elovanoides en diversas afecciones neurológicas.

01:20Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
806
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

01:29Drugs Affecting Neurotransmitter Synthesis
2.1K
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
544
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

01:21Drugs Affecting Neurotransmitter Release or Uptake
1.5K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

01:15Neurogenesis and Regeneration of Nervous Tissue
1.5K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...
