This is the first human infection of HIV that is clearly linked to gorillas and not chimpanzees. http://www.physorg.com/news168440350.html Medicine & Health Sun, 02 Aug 2009 15:00:02 EST news168440350 New research helps explain why infection with herpes simplex virus-2 (HSV-2), which causes genital herpes, increases the risk for HIV infection even after successful treatment heals the genital skin sores and breaks that often result from HSV-2. http://www.physorg.com/news168440108.html Medicine & Health Sun, 02 Aug 2009 15:00:01 EST news168440108 UCSF researchers have identified a new potential drug target for the herpes virus that causes Kaposi's sarcoma, re-opening the possibility of using the class of drugs called protease inhibitors against the full herpes family of viruses, which for 20 years has been deemed too difficult to attain. http://www.physorg.com/news168173241.html Chemistry Thu, 30 Jul 2009 11:50:52 EST news168173241 Condom use is associated with a reduced risk of contracting herpes simplex virus 2, according to a report based on pooled analysis of data from previous studies in the July 13 issue of Archives of Internal Medicine. http://www.physorg.com/news166721309.html Medicine & Health Mon, 13 Jul 2009 16:29:40 EST news166721309 Researchers at the Moores UCSD Cancer Center are injecting a modified herpes virus into melanoma tumors, hoping to kill the cancer cells while also bolstering the body's immune defenses against the disease. http://www.physorg.com/news165687558.html Medicine & Health Wed, 01 Jul 2009 17:20:27 EST news165687558 Scientists know that some cancers are triggered by viruses, which take over cellular systems and cause uncontrolled cell growth. Doctors - and patients who get shingles late in life - have also known for many years that some viruses, particularly the herpes virus, can lie dormant in a person's cells for long periods of time and then reactivate, causing disease. These viruses also cause significant disease in immunosuppressed people and those living with HIV/AIDS. http://www.physorg.com/news165515047.html Medicine & Health Mon, 29 Jun 2009 18:10:02 EST news165515047 Eczema patients at risk for serious viral infections have more severe disease, are more likely to be allergic to food and other allergens, and have a frequent history of staph infections, according to researchers at National Jewish Health and other institutions in the NIH-funded Atopic Dermatitis Vaccinia Network. The findings, published June 25 in the online version of The Journal of Allergy and Clinical Immunology, could help identify people at risk for serious complications of smallpox vaccinations, and point to defects in the skin barrier and antimicrobial-protein production as possible causes for the increased susceptibility. http://www.physorg.com/news165146799.html Medicine & Health Thu, 25 Jun 2009 11:30:01 EST news165146799 Viruses are molecular marauders, plundering cells for the resources they need to multiply. Of central importance for viruses is the ability to commandeer cellular gene expression machinery. Several human herpesviruses put the breaks on normal cellular gene expression to divert the associated enzymes and resources towards their own viral genes. Kaposi's sarcoma-associated herpesvirus (KSHV), which causes several AIDS-associated cancers, has now been shown to do this in an unexpected way, using a process that is normally protective, called polyadenylation. http://www.physorg.com/news162625056.html Biology Wed, 27 May 2009 06:38:19 EST news162625056 (PhysOrg.com) -- A new study suggests for the first time that cytomegalovirus (CMV), a common viral infection affecting between 60 and 99 percent of adults worldwide, is a cause of high blood pressure, a leading risk factor for heart disease, stroke and kidney disease. http://www.physorg.com/news161604050.html Medicine & Health Fri, 15 May 2009 11:01:32 EST news161604050 A recently completed international multi-center clinical trial has found that acyclovir, a drug widely used as a safe and effective treatment to suppress herpes simplex virus-2 (HSV-2), which is the most common cause of genital herpes, does not reduce the risk of HIV transmission when taken by people infected with both HIV and HSV-2. http://www.physorg.com/news160995218.html Medicine & Health Fri, 08 May 2009 09:54:05 EST news160995218 Scientists at the University of Melbourne have discovered the local action of immune cells in the skin, which could improve treatment of viral skin infections. http://www.physorg.com/news158328856.html Medicine & Health Tue, 07 Apr 2009 13:14:44 EST news158328856 Research in PLoS Pathogens appears to solve a long standing medical mystery by identifying a viral protein, VP16, as the molecular key that prompts herpes simplex virus (HSV) to exit latency and cause recurrent disease. http://www.physorg.com/news157355011.html Medicine & Health Fri, 27 Mar 2009 06:44:32 EST news157355011 Heterosexual men who undergo medical circumcision can significantly reduce their risk of acquiring two common sexually transmitted infections--herpes simplex virus type 2 (HSV-2), the cause of genital herpes, and human papillomavirus (HPV), which can cause cancer and genital warts, according to a report in the March 26 issue of the New England Journal of Medicine (NEJM). In the study, circumcision had no effect on their risk of becoming infected with the bacterium that causes syphilis, however. http://www.physorg.com/news157221867.html Medicine & Health Wed, 25 Mar 2009 17:45:59 EST news157221867 Scientists have discovered a new way for our immune system to combat the elusive virus responsible for cold sores: Type 1 herpes simplex (HSV-1).

While the virus they studied, HK97, only infects bacteria, well-known viruses such as herpes and HIV are also known to assemble an "intermediary" structure before morphing into its final assault-proof, infectious form. http://www.physorg.com/news153323957.html Biology Sun, 08 Feb 2009 14:00:14 EST news153323957 (PhysOrg.com) -- Kids from low-income families are much more likely to suffer from serious infections such as herpes or hepatitis A than their counterparts in wealthier households. http://www.physorg.com/news153071624.html Medicine & Health Thu, 05 Feb 2009 15:54:32 EST news153071624 A new therapy being developed at the University of Florida could, in time, produce another weapon for the fight against herpes. http://www.physorg.com/news152885637.html Medicine & Health Tue, 03 Feb 2009 12:14:18 EST news152885637
