Insights

Epstein-Barr virus (EBV)-associated cancers, particularly those affecting blood cells, have a poor prognosis. Novel therapies and East Asian drugs are crucial for improving outcomes in these rare EBV cancers.

Area of Science:

  • Oncology
  • Virology
  • Hematology

Background:

  • Virus-related cancers, including Epstein-Barr virus (EBV)-associated malignancies, represent a significant global health challenge.
  • EBV-associated cancers exhibit a poorer prognosis, especially in Western populations, due to limited research and drug development.

Purpose of the Study:

  • To review novel therapeutic strategies for EBV-associated hematopoietic cancers.
  • To highlight the importance of East Asian-developed drugs for improving patient prognosis.

Main Methods:

  • Literature review of current research on EBV-associated cancers.
  • Focus on novel therapies and specific drug development, including anti-transferrin antibody.

Main Results:

  • EBV-associated hematopoietic cancers are challenging to treat, with limited therapeutic options in Western countries.
  • Novel therapies are emerging, with a particular mention of an anti-transferrin antibody for aggressive NK leukemia.

Conclusions:

  • There is a critical need for advanced therapies for EBV-associated cancers.
  • International collaboration and utilization of drugs developed in East Asia are essential for improving outcomes.

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
