Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

2.4K
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

Nuclear Export01:42

Nuclear Export

3.7K
The nucleus restricts several proteins within and allows others to pass. The restricted proteins possess a nuclear retention sequence or NRS, anchoring them to the nuclear lamins and preventing their transport to the cytosol. The non-restricted proteins, after their synthesis, are transported to their site of action, such as the cytosol or other organelles, with the help of nuclear export signals or NES.
NES are of three types- the canonical 10-residue long leucine-rich signal and other...

Additional Subnuclear Structures02:10

Additional Subnuclear Structures

4.7K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

2.6K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.
Natural Killer Cells: The Fast Responders
NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

Nuclear Protein Sorting01:34

Nuclear Protein Sorting

4.7K
Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...

Eukaryotic Compartmentalization01:37

Eukaryotic Compartmentalization

12.5K
One of the distinguishing features of eukaryotic cells is that they contain membrane-bound organelles, such as the nucleus and mitochondria, that carry out specialized functions. Since biological membranes are only selectively permeable to solutes, they help create a compartment with controlled conditions inside an organelle. These microenvironments are tailored to the organelle's specific functions and help isolate them from the surrounding cytosol.
For example, lysosomes in the animal...

Area of Science:

  • Cell Biology
  • Immunology
  • Biophysics

Background:

  • The nuclear envelope (NE) was traditionally viewed as a passive barrier between the nucleus and cytoplasm.
  • Emerging evidence highlights the NE's active roles in cellular processes.

Purpose of the Study:

  • To review research on the NE's role in innate and adaptive immune cell function.
  • To propose the NE as a sensor and integrator of mechanical and chemical signals in immune cells.

Main Methods:

  • Literature review of studies investigating NE function in immune cells.
  • Analysis of research on mechanical forces impacting immune cell migration and function.

Main Results:

  • The NE actively contributes to regulating innate and adaptive immune cell functions.
  • Immune cells experience diverse mechanical forces during migration and in different tissue environments.
  • The NE acts as a sensor and transducer of mechanical signals.

Conclusions:

  • The NE integrates mechanical and chemical signals to precisely regulate immune cell gene transcription and function.
  • The NE should be recognized as a key organelle in immune cell function, alongside mitochondria and phagosomes.
