Resumen
Los macrófagos engullen partículas grandes usando la membrana de las reservas internas. El retículo endoplasmático se identifica como una fuente de membrana clave para este proceso crucial de fagocitosis en la inmunidad.
Área de la Ciencia:
- Inmunología Inmunología.
- Biología celular Biología celular.
Sus antecedentes:
- La fagocitosis de los macrófagos es vital para la defensa del huésped y la eliminación de los desechos celulares.
- Los fagocitos utilizan piscinas de membrana interna, como el reciclaje de endosomas, para engullir partículas más grandes que ellos mismos.
Objetivo del estudio:
- Para investigar la fuente primaria de membrana durante la fagocitosis de los macrófagos.
- Comprender los mecanismos que permiten a los fagocitos engullir partículas de gran tamaño.
Principales métodos:
- El estudio incluyó la observación de la fagocitosis de los macrófagos.
- Los investigadores investigaron el papel de los compartimentos de la membrana intracelular.
Principales resultados:

Phagocytosis
Cells pull particles inward and engulf them in spherical vesicles in an energy-requiring process called endocytosis. Phagocytosis (“cellular eating”) is one of three major types of endocytosis. Cells use phagocytosis to take in large objects—such as other cells (or their debris), bacteria, and even viruses.
Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Muscles that Move the Head
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Deglutition
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
