HIV & AIDS
Study suggests a way to stop HIV in its tracks
When HIV-1 infects an immune cell, the virus travels to the nucleus so quickly there's not enough time to set off the cell's alarm system.

Researchers use stem cells to show connection between neural cell disruption and Parkinson's disease
(Medical Xpress)—A diverse team of biologists has shown using induced pluripotent stem cells (iPSCs) that a gene mutation that causes malformations in the structure of the nuclear envelope of neural cells, is associated ...

RNA spurs melanoma development
Traditionally, RNA was mostly known as the messenger molecule that carries protein-making instructions from a cell's nucleus to the cytoplasm. But scientists now estimate that approximately 97 percent of human RNA doesn't ...

Scientists reverse a key hallmark of motor neuron disease in the laboratory
Scientists at the Francis Crick Institute and UCL have studied how proteins accumulate in the wrong parts of brain cells in motor neuron disease, and have demonstrated how it might be possible, in some cases, to reverse this.

How cytoplasmic DNA triggers inflammation in human cells
A team led by LMU's Veit Hornung has elucidated the mechanism by which human cells induce inflammation upon detection of cytoplasmic DNA. Notably, the signal network involved differs from that used in the same context in ...

Removing protein 'garbage' in nerve cells may help control two neurodegenerative diseases
Neuroscientists at Georgetown University Medical Center say they have new evidence that challenges scientific dogma involving two fatal neurodegenerative diseases—amyotrophic lateral sclerosis (ALS), and frontotemporal ...

Newly identified mechanism of p53-induced cell death could aid cancer therapy
Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research ...

Common RNA pathway found in ALS and dementia
Two proteins previously found to contribute to ALS, also known as Lou Gehrig's disease, have divergent roles. But a new study, led by researchers at the Department of Cellular and Molecular Medicine at the University of California, ...

Cytoplasm
The cytoplasm is the part of a cell that is enclosed within the plasma membrane. In eukaryotic cells, the cytoplasm contains organelles, such as mitochondria, which are filled with liquid that is kept separate from the rest of the cytoplasm by biological membranes. The contents of the cell nucleus are not part of the cytoplasm and are instead called the nucleoplasm. The cytoplasm is the site where most cellular activities occur, such as many metabolic pathways like glycolysis, and processes such as cell division. The inner, granular mass is called the endoplasm and the outer, clear and glassy layer is called the cell cortex or the ectoplasm.
The part of the cytoplasm that is not held within organelles is called the cytosol. The cytosol is a complex mixture of cytoskeleton filaments, dissolved molecules, and water that fills much of the volume of a cell. The cytosol is a gel, with a network of fibers dispersed through water. Due to this network of pores and high concentrations of dissolved macromolecules, such as proteins, an effect called macromolecular crowding occurs and the cytosol does not act as an ideal solution. This crowding effect alters how the components of the cytosol interact with each other.
