They believe the herpes simplex virus is a significant factor in developing the debilitating disease and could be treated by antiviral agents such as acyclovir, which is already used to treat cold sores and other diseases caused by the herpes virus. Alzheimer's disease (AD) is characterised by progressive memory loss and severe cognitive impairment.
Professor Ruth Itzhaki and her team at the University's Faculty of Life Sciences have investigated the role of herpes simplex virus type 1 (HSV1) in AD, publishing their very recent, highly significant findings in the Journal of Pathology. Most people are infected with this virus, which then remains life-long in the peripheral nervous system, and in 20-40% of those infected it causes cold sores.
The team discovered that the HSV1 DNA is located very specifically in amyloid plaques: 90% of plaques in Alzheimer's disease sufferers' brains contain HSV1 DNA, and most of the viral DNA is located within amyloid plaques. The team had discovered much earlier that the virus is present in brains of many elderly people and that in those people with a specific genetic factor, there is a high risk of developing Alzheimer's disease.
The team's data strongly suggest that HSV1 has a major role in Alzheimer's disease and point to the usage of antiviral agents for treating the disease, and in fact in preliminary experiments they have shown that acyclovir reduces the amyloid deposition and reduces also certain other feature of the disease which they have found are caused by HSV1 infection. Professor Itzhaki explains: "We suggest that HSV1 enters the brain in the elderly as their immune systems decline and then establishes a dormant infection from which it is repeatedly activated by events such as stress, immunosuppression, and various infections. The team now hopes to obtain funding in order to take their work further, enabling them to investigate in detail the effect of antiviral agents on the Alzheimer's disease-associated changes that occur during HSV1 infection, as well as the nature of the processes and the role of the genetic factor. This is a microscopic section from the edge of one of a group of small round clear vesicles on the skin, just above the lip.

This tab also contains .pdf files of several of my old papers that are not available on the Internet. The virions are drawn to scale, but artistic license has been used in representing their structure. Virions have accumulated in the normally narrow spaces between neurons as a result of budding from the intracytoplasmic (Golgi) membranes and exocytosis via membrane fusion. This is an ultra-thin section of the salivary gland of an Aedes triseriatus (Say) mosquito, 21 days after infection, showing large numbers of virions within the lumen of an upstream divereticulum of the salivary space.
This image has been "borrowed" so often for various public uses that many people think that all Ebola virions look just like thisa€”indeed, in the film Outbreak every virion seen looked just like this. In this case, some of the filamentous virions are fused together, end-to-end, giving the appearance of a "bowl of spaghetti." Negatively stained virions. These inclusions may be dramatic in scale, beautiful in appearance, but this is "a terrible beauty" (Yeats). This is the same ultra-thin section of an infected cell in a cell culture as above, only colorized. Negatively stained virions showing surface projections which contain the receptors by which the virus attaches to host respiratory tract epithelial cells.
This is an ultra-thin section of the brain of a mouse infected with La Crosse virus (family Bunyaviridae, genus Bunyavirus) at six days post-infection when the mouse was moribund. Virions have been penetrated by the negative contrast stain; the fine surface projections and envelope (derived from Golgi membrane of the infected cell) that are characteristic of viruses like this (family Bunyaviridae, genus Bunyavirus) are clear, but viral nucleocapsids, which are very fine strands, are not.
7, 2008) a€” The virus behind cold sores is a major cause of the insoluble protein plaques found in the brains of Alzheimer's disease sufferers, University of Manchester researchers have revealed. Another future possibility is vaccination against the virus to prevent the development of the disease in the first place.
It affects over 20 million people world-wide, and the numbers will rise with increasing longevity. The team had previously shown that HSV1 infection of nerve-type cells induces deposition of the main component, beta amyloid, of amyloid plaques. They very much hope also that clinical trials will be set up to test the effect of antiviral agents on Alzheimer's disease patients. Notice the mauve to pink homogenous intranuclear inclusions in the epithelial cells of the epidermis.

This is a 180Mb .pdf file, which takes about 2 minutes to download on my home computer, but it is the lowest resolution (smallest file) possible. In some, the cross-sectional structure of capsid and envelope are shown, with a representation of the genome; with the very small virions, only their size and symmetry are depicted.


Virions have accumulated in the space between cells as a result of budding from the surface membrane of infected cells. In this infection large numbers of the 60 nm (nanometer) spherical virions crowd the salivary space, ready to be transmitted to the next vertebrate host when the mosquito seeks a blood meal. In fact, Ebola virions are extremely varied in appearance -- they are flexible filaments with a consistent diameter of 80 nm (nanometers), but they vary greatly in length (although their genome length is constant) and degree of twisting.
In fact, Ebola virions are extremely varied in appearance a€” they are flexible filaments with a consistent diameter of 80 nm (nanometers), but they vary greatly in length (although their genome length is constant) and degree of twisting. Here, virion budding is occurring "perpendicular" to the plane of the plasma membrane -- in other instances budding has been seen to occur in "parallel" fashion, with the entire virion nucleocapsid first lying in contact with the inner face of the plasma membrane and budding occurring along its entire length. Herpes simplex virus infection becomes latent, that is it becomes invisible after a fever blister episode, but the virus persists, in ganglia at the floor of the brain; when conditions are right the virus can re-emerge. Adenoviruses replicate in the nucleus of cells and as seen here they may reach extraordinary concentrations.
Rotaviruses replicate in the cytoplasm of cells, usually in association with granular inclusions ("virus factories") as shown here. Virions (100nm in diameter) are accumulating within intracytoplasmic (Golgi) vesicles as a result of budding. Together, these findings strongly implicate HSV1 as a major factor in the formation of amyloid deposits and plaques, abnormalities thought by many in the field to be major contributors to Alzheimer's disease.

The highest resolution file, suitable for printing, is also available, but I would have to send it via Dropbox. Classical negative contrast images of coronaviruses are really not the way they look when in their native state. In this infection very large numbers of the 60 nm (nanometer) spherical virions are produced quickly and as quickly the cells are destroyed.
When isometric particles are crowded together they form six-fold, three-dimensional arraysa€”when such arrays are sectioned one sees various planes of section because the pseudocrystalline array is not perfect. The most common sites for Herpes simplex virus infections (either primary or reactivation) are skin and mucus membranes. HSV type I is seen most often in oral cavity, while HSV type II is more commonly a sexually transmitted disease. Here, the top micrograph represents the classical image and the bottom micrograph the way coronaviruses look in their native state.
Native virions are actually so heavily covered with peoplmers that virions might not be recognized if only the classical images are in mind. This is an ultra -- thin section of the small intestine of an infant mouse at two days post-infection when the mouse was moribund. Virions have accumulated upon the plasma membrane of this intestinal epithelial cell as a result of transport from sites of virion production in the endoplasmic reticulum and exocytosis via membrane fusion -- the virions then stick to the outer surface of the cell.
