Kaposi's sarcoma-associated herpesvirus (KSHV) is the ninth known human herpesvirus.It is also called Human herpesvirus 8, or HHV-8 in short. [2] This virus causes Kaposi's sarcoma, a cancer commonly occurring in AIDS patients, [3] as well as primary effusion lymphoma, [4] HHV-8-associated multicentric Castleman's disease and KSHV inflammatory cytokine syndrome.

The virus activates a subset of T-helper cells called Th1 cells. The result is a proliferation of Th1 cells and overproduction of Th1-related cytokines (mainly IFN-γ and TNF-α). Feedback mechanisms of these cytokines cause a suppression of the Th2 lymphocytes and a reduction of Th2 cytokine production (mainly IL-4, IL-5, IL-10 and IL-13). The ...
A blood-borne disease is a disease that can be spread through contamination by blood and other body fluids. Blood can contain pathogens of various types, chief among which are microorganisms , like bacteria and parasites , and non-living infectious agents such as viruses .
Because chronic viral hepatitis is so common, and liver cancer so deadly, liver cancer is one of the most common causes of cancer-related deaths in the world, and is especially common in East Asia and parts of sub-Saharan Africa. [citation needed] Human papillomaviruses (HPV) also cause many cancers.
Percentage of people infected with hepatitis C in 2015. The hepatitis C virus is the cause of hepatitis C and some cancers such as liver cancer (hepatocellular carcinoma, abbreviated HCC) and lymphomas in humans. [1] [2] [3] An oncovirus or oncogenic virus is a virus that can cause cancer. [4]
But a new study, which included some of the same data as the January study, argues only as much as 30 percent of cancers fall under the so-called "bad luck hypothesis." Instead, the main causes ...
Skin infections with HPV can cause noncancerous skin growths called warts (verrucae). Warts are caused by the rapid growth of cells on the outer layer of the skin. [30] While cases of warts have been described since the time of ancient Greece, their viral cause was not known until 1907. [17]
T-cells attack cancer cells and cause them to become inflamed and die, but your body makes a limited amount of T-cells, and if there is too much cancer to fight, the T-cells can’t keep up ...
