ApoE4 genotype is the most prevalent and also clinically most important risk factor for late-onset Alzheimer’s disease ( AD ) . Available evidence suggests that the root cause for this increased risk is a trafficking defect at the level of the early endosome . ApoE4 differs from the most common ApoE3 isoform by a singl...
Alzheimer’s disease is a degenerative condition that destroys connections between brain cells leading to memory loss , confusion and difficulties in thinking . Apolipoprotein E is a protein that carries fatty substances called lipids and cholesterol around the brain , and plays an important role in repair mechanisms . ...

Repetitive proteins are thought to have arisen through the amplification of subdomain-sized peptides . Many of these originated in a non-repetitive context as cofactors of RNA-based replication and catalysis , and required the RNA to assume their active conformation . In search of the origins of one of the most widespr...
All life is built upon the chemical activity of proteins . For this activity , proteins need to fold into specific 3D structures . Protein folding is complicated and easily disrupted , and its evolutionary origin remains poorly understood . A possibility is that folded proteins arose through different genetic processes...

Sexual maturation must occur on a controlled developmental schedule . In mammals , Makorin3 ( MKRN3 ) and the miRNA regulators LIN28A/B are key regulators of this process , but how they act is unclear . In C . elegans , sexual maturation of the nervous system includes the functional remodeling of postmitotic neurons an...
Most animals develop from juveniles , which cannot reproduce , to sexually mature adults . The most obvious signs of this transition are changes in body shape and size . However , changes also take place in the brain that enable the animals to adapt their behavior to the demands of adulthood . For example , fully fed a...

Neuroscientists have long sought to understand how the brain works by analyzing its electrical activity . Placing electrodes on the scalp or lowering them into the brain itself reveals rhythmic waves of activity known as oscillations . These arise when large numbers of neurons fire in synchrony .

Although humans have thousands of genes , only a fraction of these are expressed in any given cell . Each cell type expresses only the genes that are relevant to its particular job or that are necessary for general cell maintenance . Even these genes are not expressed all the time: most cells express genes in bursts , ...

Gram-negative bacteria import essential nutrients such as iron and vitamin B12 through outer membrane receptors . This process utilizes proton motive force harvested by the Ton system made up of three inner membrane proteins , ExbB , ExbD and TonB . ExbB and ExbD form the proton channel that energizes uptake through To...
Many biological processes that are essential for life are powered by the flow of ions across the membranes of cells . Similar to how energy is stored in the water behind a dam , energy is also stored when the concentration of ions on one side of a biological membrane is higher than it is on the other . When these ions ...

Long lasting pyrethroid treated bednets are the most important tool for preventing malaria . Pyrethroid resistant Anopheline mosquitoes are now ubiquitous in Africa , though the public health impact remains unclear , impeding the deployment of more expensive nets . Meta-analyses of bioassay studies and experimental hut...
In recent years , widespread use of insecticide-treated bednets has prevented hundreds of thousands cases of malaria in Africa . Insecticide-treated bednets protect people in two ways: they provide a physical barrier that prevents the insects from biting and the insecticide kills mosquitos that come into contact with t...

Molecular and cellular processes in neurons are critical for sensing and responding to energy deficit states , such as during weight-loss . Agouti related protein ( AGRP ) -expressing neurons are a key hypothalamic population that is activated during energy deficit and increases appetite and weight-gain . Cell type-spe...
Humans and other animals must get adequate nutrition in order to survive . As a result , the body has several systems that work side by side to maintain a healthy body weight and ensure that enough food gets eaten to provide the energy that the body needs . Problems with these systems can contribute towards obesity and...

The inner ear is a fluid-filled closed-epithelial structure whose function requires maintenance of an internal hydrostatic pressure and fluid composition . The endolymphatic sac ( ES ) is a dead-end epithelial tube connected to the inner ear whose function is unclear . ES defects can cause distended ear tissue , a path...
The most internal part of the human ear , the inner ear , is essential for us to hear and have a sense of balance . It is formed by a complex series of connected cavities filled by a liquid . When sound waves and changes in the position of the body make this liquid move , specialized ‘hair’ cells can detect these subtl...

Organisms are said to be diploid when they carry two copies of each chromosome in their cells , one from each of their biological parents . But in order for each parent to only pass on one copy of their own chromosomes , they need to make haploid cells , which only carry one copy of each chromosome . These cells form b...

Osteocalcin ( OCN ) is an osteoblast-derived hormone with pleiotropic physiological functions . Like many peptide hormones , OCN is subjected to post-translational modifications ( PTMs ) which control its activity . Here , we uncover O-glycosylation as a novel PTM present on mouse OCN and occurring on a single serine (...
Bones provide support and protection for organs in the body . However , over the last 15 years researchers have discovered that bones also release chemicals known as hormones , which can travel to other parts of the body and cause an effect .

Giant lipid vesicles are closed compartments consisting of semi-permeable shells , which isolate femto- to pico-liter quantities of aqueous core from the bulk . Although water permeates readily across vesicular walls , passive permeation of solutes is hindered . In this study , we show that , when subject to a hypotoni...
All living cells are surrounded by a membrane that water can pass through . However , water often contains other molecules called solutes , and many of these cannot pass through the cell membrane . If the concentration of solutes outside the cell is , say , suddenly decreased , then water molecules will tend to move in...

More than 100 years ago , Nobel-prize winning geneticist Thomas Hunt Morgan and his colleagues discovered that some fruit flies inherited genetic mutations that caused their body color to change . The yellow flies had a mutation in one specific gene and these mutants did not only look different from normal flies , they...

Adult stem cells can divide to produce cells that can develop into one of many different specialist cell types in a tissue , and so are vitally important for tissue repair and maintenance .
