Crosstalk between hemostasis and immunity in cancer pathogenesis

Area of Science:

• Immunology
• Hematology
• Oncology

Background:

• The hemostatic and immune systems exhibit bidirectional crosstalk, crucial for host defense against injury and infection.
• This crosstalk involves complex interactions that maintain vascular integrity, clear pathogens, and remove cellular debris.

Purpose of the Study:

• To explore the intricate relationship between hemostasis and immunity in the context of cancer biology.
• To identify key molecular bridges linking these systems that are exploited by malignancies.

Main Methods:

• Review of studies over the last three decades focusing on hemostasis-immune system interplay.
• Analysis of specific molecular components, including the platelet/fibrinogen axis, protease-activated receptor-1 (PAR-1), and protease-activated receptor-2 (PAR-2).

Main Results:

• Malignancies leverage hemostasis-immunity crosstalk to promote tumorigenesis, stroma formation, and metastasis.
• Platelet/fibrinogen, PAR-1, and PAR-2 act as critical bridges, regulating immune functions that support cancer progression.
• These hemostatic components influence inflammation-driven malignancy, metastasis, and immune evasion.

Conclusions:

• Understanding the mechanisms coupling hemostasis and immunity offers potential for novel cancer prevention and treatment strategies.
• Targeting these crosstalk pathways, particularly the identified molecular bridges, could lead to new therapeutic interventions for various cancers.
