Table 1 Pros and Cons of using each TAA in the development of CAR-T cells in prostate cancer

From: CAR-T cell therapy: a potential new strategy against prostate cancer






Serine protease

1) Almost exclusively expressed by prostate epithelial cells

2) Stimulates cytotoxic lymphocytes in vivo [45]

It is a prostate-specific but not tumor-specific antigen


Tyrosine phosphatase protein

1) Secreted by benign and malignant prostate cells

2) Stimulates CTLs in vivo [45]

1) More highly expressed in Gleason score 6 and 7 tumors than in higher Gleason score tumors.

2) Expressed in the placenta, kidneys and testes, and also in gastric, breast and colon cancer


Serine protease

Expression increases with both high Gleason score and metastasis

PSCA has also been found expressed in other cancer types


Transmembrane protein

Enhances cytokine production

Also expressed in low levels in salivary glands, brain and kidneys


Transmembrane protein

Show significance as a biomarker for early cancer development

Not a prostate cancer- specific antigen
