Resumen
El olor influye en el envejecimiento y la vida útil de las moscas de la fruta. Los sentidos olfativos, particularmente relacionados con los nutrientes, pueden alterar la esperanza de vida, incluso revertir los beneficios de la restricción dietética.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Genética La genética.
- Investigación sobre el envejecimiento de la investigación.
Sus antecedentes:
- El sentido del olfato es antiguo y se conserva en todas las especies.
- Se sabe que las neuronas olfativas y gustativas en Caenorhabditis elegans regulan el envejecimiento.
- La restricción dietética es un modulador conocido de la esperanza de vida.
Objetivo del estudio:
- Para investigar el papel del olfato en la fisiología adulta y el envejecimiento en Drosophila melanogaster.
- Para determinar si la exposición al olor afecta la esperanza de vida e interactúa con la restricción dietética.
- Para explorar la conservación evolutiva de la regulación olfativa de la vida útil.
Principales métodos:
- Exposición de Drosophila melanogaster a los olores derivados de los nutrientes.
- Mutación genética del receptor del olor Or83b.
- Evaluación de la esperanza de vida, el metabolismo adulto y la resistencia al estrés.
Principales resultados:
- La exposición a los olores de nutrientes moduló la esperanza de vida y revirtió parcialmente los efectos de la restricción dietética.
- La mutación de Or83b condujo a defectos olfativos, un metabolismo alterado y una vida útil prolongada.

Gustation
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Introduction to Special Senses
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive functions.
Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
The Physiology of Taste
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the diffusion of...
Salivary Glands and Saliva
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
