Your question: Why does EBV cause cancer?

What cancer causing mutations result from EBV infection?

EBV has been implicated in the pathogenesis of Burkitt’s lymphoma, Hodgkin’s disease, non-Hodgkin’s lymphoma, nasopharyngeal carcinoma, and lymphomas, as well as leiomyosarcomas arising in immunocompromised individuals.

How does EBV cause lymphoma?

The three major types of B cell malignancy linked to EBV are the Burkitt, Hodgkin and diffuse large B cell lymphomas (BL, HL and DLBCL). As illustrated in figure 1, these tumours are thought to emanate from progenitor cells arrested at distinct stages of GC transit or post-GC development.

What cancers does EBV cause?

EBV infection increases a person’s risk of getting nasopharyngeal cancer (cancer of the area in the back of the nose) and certain types of fast-growing lymphomas such as Burkitt lymphoma. It may also be linked to Hodgkin lymphoma and some cases of stomach cancer.

Why is EBV oncogenic?

Latent membrane protein 1

LMP1 is considered the EBV oncogene as it can transform rodent fibroblasts in vitro and is essential for B-cell transformation (Wang et al., 1985). Transgenic mice that express LMP1 in B cells have increased development of B cell lymphomas (Kulwichit et al., 1998).

  • Extreme fatigue.
  • Rash.

  • Headache.
  • Enlarged spleen (splenomegaly)
  • Swollen liver.
  • Swollen lymph nodes.

What lymphomas are associated with EBV?

The Epstein–Barr virus (EBV) is linked to various B-cell lymphomas, including Burkitt lymphoma (BL), classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL) at frequencies ranging, by routine techniques, from 5 to 10% of cases in DLBCL to >95% in endemic BL.

What does positive Epstein-Barr test mean?

If someone is positive for VCA-IgM antibodies, then it is likely that the person has an EBV infection and it may be early in the course of the illness. If the individual also has symptoms associated with mono, then it is most likely that the person will be diagnosed with mono, even if the mono test was negative.

Is Epstein-Barr related to HPV?

Two DNA viruses, Epstein-Barr virus (EBV) and human papillomavirus (HPV), are associated with 38% of all virus-associated cancers. The probability of one patient infected with these two distinct types of viruses is increasing.

Can EBV be cured?

Although no medicine can cure an EBV infection, you can take these steps at home to ease your symptoms: Get plenty of rest. Drink a lot of water and other liquids to stay hydrated. Suck on lozenges or ice pops, or gargle with warm salt water, to make your sore throat feel better.
