Lymphoid Cells and Tissues01:18

Lymphoid Cells and Tissues

2.6K
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Intralumenal Vesicles and Multivesicular Bodies01:38

Intralumenal Vesicles and Multivesicular Bodies

4.4K
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

5.9K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Primary Lymphoid Organs01:16

Primary Lymphoid Organs

14.2K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

12.9K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

6.6K
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...

Area of Science:

  • Virology
  • Oncology
  • Genetics

Context:

  • Epstein-Barr virus (EBV), a herpesvirus, is linked to various lymphomas.
  • While EBV's role in Burkitt lymphoma is understood, its mechanisms in other lymphoid tumors remain unclear.
  • Intragenic deletions in EBV genomes from lymphomas have been recently observed.

Purpose:

  • To review the role of Epstein-Barr virus in lymphomagenesis.
  • To focus on the impact of intragenic deletions within the EBV genome.
  • To elucidate the mechanisms of EBV-induced lymphoid tumors beyond Burkitt lymphoma.

Summary:

  • EBV, a double-stranded DNA virus, is associated with numerous lymphomas.
  • The study highlights frequent intragenic deletions in the EBV genome within lymphomas.
  • Deletion of a critical viral gene essential for replication was shown to promote lymphomagenesis in a mouse model.

Impact:

  • Provides insights into EBV's oncogenic potential beyond known mechanisms.
  • Underscores the significance of intragenic deletions in EBV-associated lymphomagenesis.
  • Contributes to understanding the complex interplay between viral genetics and cancer development.
