Resumen
Un remanente de la membrana ciliar primaria permanece unido a la madre centríola. Esta membrana se hereda asimétricamente durante el desarrollo de la formación de la neocórtex.
Área de la Ciencia:
- Biología celular Biología celular.
- Neurociencia del desarrollo neurológico.
- Biología del centrosoma Biología del centrosoma.
Sus antecedentes:
- Tradicionalmente se cree que el cilium primario, un orgánulo celular, se desmonta antes de la división celular (mitosis).
- Se cree que este desmontaje permite a los centrosomas formar el huso mitótico esencial para la división celular.
Objetivo del estudio:
- Para investigar el destino de la membrana ciliar primaria durante la mitosis.
- Para determinar si el remanente del cilium primario juega un papel en la división celular asimétrica en el neocórtex en desarrollo.
Principales métodos:
- Se utilizaron técnicas avanzadas de microscopía para visualizar los cilios primarios y los centrosomas durante la mitosis.
- Rastreó la herencia de los componentes centrosomales durante el desarrollo neocortical in vivo.
Principales resultados:
- Se demostró que una porción de la membrana ciliar primaria permanece unida al centriolo madre después del desmontaje.
- Se demostró que este remanente de la membrana ciliar se distribuye asimétricamente a las células hijas durante el desarrollo neocortical.
Conclusiones:
- Desafía la noción de desmontaje completo del cilium primario antes de la mitosis.
- Sugiere un nuevo mecanismo para la herencia asimétrica que involucra los restos de la membrana ciliar, impactando el destino celular en el neocórtex en desarrollo.

Mechanism of Ciliary Motion
5.0K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Microtubules in Signaling
1.5K
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Flashbulb Memory
516
A flashbulb memory is a highly vivid and detailed memory, often linked to events of significant emotional impact. These memories stand out in contrast to everyday memories due to their clarity and the precision with which they are recalled. The strong emotions associated with the event act as a catalyst, ensuring that specific details, such as one's location, actions, and even peripheral elements, are etched into memory with remarkable accuracy. For example, many people can vividly recall...

Cells of the Adaptive Immune Response
6.9K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
