What is Lage 1a?

NY-ESO-1 (CTAG1B) and LAGE1A (CTAG2) are tumour associated antigens (TAA) that share the SLLMWITQC peptide bound to human leukocyte antigen HLA-A*02 and are expressed in various cancers.

What is an NY-ESO-1 receptor?

NY-ESO-1 is an archetypical example of a CTA with restricted expression to germ cells and placental cells and re-expression in tumor cells. During embryonic development, NY-ESO-1 expression can be detected as early as 13 weeks and is the highest at 22–24 weeks (20).

What is immune escape mechanism?

Antigenic escape, immune escape, immune evasion or escape mutation occurs when the immune system of a host, especially of a human being, is unable to respond to an infectious agent: the host’s immune system is no longer able to recognize and eliminate a pathogen, such as a virus.

What method would you use to isolate the T cells and how would you identify them?

The use of MHC-peptide tetramers is a canonical method to identify and study a certain antigen-specific T cell subset (69–71). For ACT, tetramers were used to isolate and expand tumor antigen-specific T cells (72).

How do tumor cells escape immune surveillance?

2.3. As alluded to above, tumors can evade immune surveillance by crippling CTL functionality via production of several immune suppressive cytokines, either by the cancer cells or by the non-cancerous cells present in the tumor microenvironment, especially including immune cells and epithelial cells.

What is tumor escape?

The specific ways by which a particular cancer cell evades immunosurveillance are known as tumor escape mechanisms (Khong & Restifo, 2002). These specific adaptations allow malignant cells to survive and replicate in the microenvironment of the host. Tumor cells acquire tumor escape mechanisms through genetic mutation.

What are examples of immune checkpoint inhibitors?

Examples of checkpoint inhibitors include pembrolizumab (Keytruda), ipilimumab (Yervoy), nivolumab (Opdivo) and atezolizumab (Tecentriq).

Where is carcinoma found in the body?

Carcinoma is a type of cancer that starts in cells that make up the skin or the tissue lining organs, such as the liver or kidneys. Like other types of cancer, carcinomas are abnormal cells that divide without control. They are able to spread to other parts of the body, but don’t always.
