By age 40, nearly 90% of adults have been exposed to the herpes simplex virus-1 (HSV-1), which causes cold sores.
Until now, research has generally concentrated on keeping HSV1 inactive — and preventing cold sores from ever showing up. Understanding how to override the microRNA could allow scientists to activate the virus and then kill it using acyclovir.
The theory is that by activating the virus, then preventing it from returning to hibernation, which is when researchers think it gains strength, it can be completely eradicated.
Cullen and his colleagues, as well as several biotech firms, are already investigating such treatments and how best to deliver them. OverviewHerpes simplex, a common viral disease, is caused by two strains of the herpes simplex virus (HSV). The initial infection (primary stage) of oral herpes is generally asymptomatic and is acquired through person to person contact such as kissing.
The stages of genital herpes are very similar to oral herpes with an initial stage that manifests with few symptoms and is less contagious.
For both genital and oral herpes, the dormancy period involves the virus "resting" within the nervous tissue around the initially infected area. Herpes is commonly diagnosed based upon the symptoms described above paired with frequent recurrence in the same area. Once diagnosed with herpes, managing the disease includes caring for sores during outbreaks as well as preventing their recurrence. Since genital and oral herpes are extremely common in the United States, with an estimate of 45 million people or one out of every five infected, there are many places to turn for support. Viral infections or exacerbations are still the most difficult problem in medicine to date. Herpes Simplex Keratitis Herpes simplex keratitis is a common form of infection affecting the cornea (the clear transparent dome-shaped window of the eye).
The dendritic ulcer causes photophobia, tearing, blurred vision, redness of the eye and pain. The virus can also cause conjunctivitis with the presence of follicles in the conjunctiva, giving it a bumpy appearance.
Steroid drops can exacerbate the dendritic ulcer and should only be used under supervision by an ophthalmologist. Steroid drops can result in the dendritic ulcer becoming much larger and affecting a wider area of the cornea – known as a geographic ulcer. The virus lies dormant in the trigeminal nerve and can become reactivated during times of illness or stress or when you are feeling generally run-down. Herpes simplex can affect other areas of the eye, causing trabeculitis (inflammation of the drainage area of the eye) leading to raised pressure within the eye and inflammation of the coloured part of the eye – uveitis. Repeated recurrences usually lead to scarring and clouding of the cornea, a loss of sensation in the cornea and vessels growing across the cornea, sometimes causing lipid being deposited in the cornea (see picture below). If this happens, sight is impaired and a corneal graft may become necessary to restore vision.
But the Duke researchers took the opposite tack: figuring out precisely how to switch the virus from latency to its active stage.
Cullen believes that a drug could be developed to block the microRNA that suppress HSV-1 into latency; once it's active, acyclovir can be used to destroy the virus permanently.
Long-term prophylaxis of cold sores is indicated when you get cold sores frequently, at a rate of about 6 or more times per year.

This infection is caused by the herpes simplex virus, the same virus which causes cold sores around the mouth. The dendritic ulcer can be diagnosed with the help of fluorescein eye drops which stain it a brilliant green colour which is then detected using the cobalt blue filter on the slit lamp. However, with prompt treatment by a corneal specialist, these complications can be prevented or minimised.


Herpes simplex can also cause swelling of the cornea known as a disciform keratitis where the cornea develops an immune reaction to the virus. In a few extreme cases, it can also affect the back of the eye, causing an optic neuritis and inflammation of the retinal vessels causing acute retinal necrosis.Treatment of Herpes simplex infectionTreatment is usually successful with the application of an antiviral ointment or gel to the eye.
For those who do, however, cold sores are a painful and permanent nuisance, always erupting in the same location, at the original site of infection on the lips or mouth.
In its latent stage, HSV-1 produces a single molecular product, called latency-associated transcript RNA, or LAT RNA.
Cullen suggests that this new research may also eventually be applied to other latent viruses, such as herpes simplex virus-2 (HSV-2), which causes genital herpes, or the chicken pox virus, which causes shingles in adults. The potential side effects of daily oral medication must be considered with infrequent cold sores. The rashes can happen at any site of the body but here we shall talk about rashes in inner thighs that carry its own significance. How does it affect the eyeThe most common presentation of herpes simplex keratitis is the dendritic ulcer on the cornea which resembles a branching tree. Worse yet, once you're infected with the virus that causes them, you're stuck with it for good. Once HSV-1 enters the body it hunkers down for life, most of the time hiding dormant in the cranial nerves near the spine. Unlike most messenger RNA, LAT RNA doesn't produce proteins, so scientists have never been able to determine LAT RNA's exact function.
Cullen warns that some patients, especially those suffering genital herpes, may have to take acyclovir on a regular basis (HSV-2 is a hardier virus), but for people with HSV-1, the virus could be eradicated with just one dose.
Nevertheless, most of the rashes are treated in the same way – depending upon the cause.
In most cases, the ulcer heals with no sequelae but sometimes, faint scars remain on the cornea at the site of the previous ulcer. But landmark research reported today by microbiologists at Duke University may offer the potential for a cure. The virus can be triggered by outside stress, such as exposure to sunlight, a fever or emotional distress. But by inserting the LAT RNA into mice, Cullen found that it breaks down into even smaller strands called microRNA.
Several recurrences may result in the formation of deep ulcers, permanent scarring, and a loss of feeling when the eye is touched. After it's active and a cold sore appears, it's treatable with the drug acyclovir, marketed under the name Zovirax, which kills replicating HSV-1. Researchers then discovered that it was the microRNA that blocked production of the protein that activates HSV-1. In some instances, samples of representative lesions are taken and tested for the presence of the HSV1 or HSV2 virus.
The herpes simplex virus may also cause blood vessels to grow onto the cornea and this alone can lead to significant visual impairment.
But the mystery has been how to eliminate the virus while it's hiding, before it produces unsightly symptoms.
Contact dermatitis or skin inflammation is due to adverse reaction to something that is allergic to your skin.
This may include chemicals used in bathing soap, shower gel or detergent (used to wash the undergarments).
It can also happen due to thighs rubbing each other, which is quite common in a person with fatty thighs.
The rubbing of skins of inner thighs result in irritation (called intertrigo) that causes redness and inflammation of the skin.The rash on inner thighs may also happen due to contact with poisonous component found in herbs like poison oak or ivy, or present in the insect’s sting or animal’s bite. For instance, tick’s bite can cause Lyme disease that first forms a round shaped wound and then turns into rashes. Disease like Rocky Mountain spotted fever can also cause rashes on arms and inner thighs (legs).


While it is difficult to know which food can create allergic response, some common foods include avocado, peanut, shellfish, strawberry that are known to cause rashes on the body including inner thighs.
In most of the cases, body’s response to allergy is quite controllable, but in some unfortunate cases it becomes fatal, and the sufferer faces life-threatening reactions affecting not only skin but also kidneys, intestines, joints and heart.
In such cases, profuse sweating, vomiting, and difficulty in breathing are common symptoms. Diseases that may cause Rashes on Inner ThighsOther than allergic substances and chemicals, there are some health ailments known to cause rashes on the body and so on the inner thighs.
Psoriasis, impetigo and eczema are few of the diseases that are known to produce rashes or skin eruption. Inner thigh rashes are quite common in patients diagnosed with psoriasis.Apart from above mentioned health ailments, some autoimmune diseases are also known to cause rashes all across the body including inner thighs. Autoimmune disease is a condition wherein the body cells are attacked by their own body immune system that otherwise happens only in case of invasion of foreign bodies (such as microorganisms).
This is because inner thighs are the portions where the friction of skins happens during cycling. It is also called as saddle sores.Inner thigh rashes due to cycling first appear as a hot spot in one of the thighs.
If this stage is ignored, the second phase comes wherein the rash becomes intense and turns into a condition called folliculitis. Folliculitis is marked by a bump or blister at the hair follicles and might be filled with pus. If the sufferer keeps on riding and ignores it, the rash enters into the final stage of large bump that is hot, swollen and highly tender. They have chafed skin because of cloth (underwear, shorts or pants) rubbing with inner thigh skin.
Some special types of yeast or fungus grow on the human skin and give rise to rashes and many other skin lesions. Ringworm, candida, acne vulgaris are few conditions that could be associated with inner thigh rashes. If the diaper is filled with urine or excreta and not changed for long hours, it may cause irritation to the baby’s skin. In most of the cases, keeping the area hygienic and changing the nappies frequently solve the problem.
In some cases, local antibiotic and anti fungal cream is applied as advised by pediatricians.
This group of drugs help to reduce the inflammation of the skin and thus helps in alleviating itching.
Anti-allergic drugsAnti-allergic drugs are prescribed as traditional practice in dermatology. Some healthcare providers prefer prescribing moisturizing creams to treat inner thigh rashes. Vitamin D and retinoid creams are also helpful maintaining the good health of the skin.If inner thigh rashes are because of psoriasis, the line of treatment is different.
This component is used as an active ingredient in skin creams and gels to reduce the symptoms of psoriasis and thus help treat the inner thigh rashes.
Nevertheless, retinoid can create severe side effects and hence is to be taken under strict medical supervision. Immunosuppressant drugsDrugs such as cyclosporine can help lessen the severity of psoriasis and thus fade the rashes and make them milder in color. Since this class of drugs are known to damage kidneys and affect blood pressure, strict medical supervision is required for this course of medication.
