TSLP: contrasting roles in cancer

Area of Science:

• Immunology
• Oncology
• Cytokine Biology

Background:

• Thymic stromal lymphopoietin (TSLP) is an alarmin cytokine with diverse biological activities.
• TSLP signals through a heterodimeric receptor complex involving TSLP receptor (TSLPR) and IL-7Rα.
• Primarily produced by epithelial cells, TSLP also originates from immune cells and cancers, influencing inflammation, angiogenesis, and tumorigenesis.

Purpose of the Study:

• To review recent advances in TSLP immunobiology concerning human and experimental cancers.
• To discuss the dual role of TSLP as a Janus cytokine in tumorigenesis.
• To highlight the potential of anti-TSLP therapies in cancer treatment.

Main Methods:

• Literature review of TSLP's role in cancer.
• Analysis of TSLP's involvement in immune cell activation.
• Examination of preclinical data, including the efficacy of anti-TSLP monoclonal antibodies in cancer models.

Main Results:

• TSLP plays a significant role in the development of various human hematologic and solid tumors.
• Contradictory findings exist regarding TSLP's precise role in different cancer types.
• An anti-TSLP monoclonal antibody demonstrated protective effects in a mouse model of colorectal cancer.

Conclusions:

• TSLP is implicated in both cancer development and progression.
• Further research into TSLP's multifaceted role in tumorigenesis is crucial.
• Targeting TSLP with monoclonal antibodies represents a promising therapeutic strategy for certain cancers.
