Components of the Lectin Pathway of Complement in Solid Tumour Cancers

Area of Science:

• Immunology
• Oncology

Background:

• The complement system, a key part of innate immunity, has three activation pathways: classical, alternative, and lectin.
• It interacts with cellular innate immunity and acquired immunity components, influencing homeostasis.
• Dysregulation, including over- or chronic activation, can be detrimental.

Purpose of the Study:

• To review the dual role of the lectin pathway of complement activation in human solid cancers.
• To highlight the cross-talk between the lectin pathway and other enzyme-dependent cascades in cancer.

Main Methods:

• Literature review focusing on the lectin pathway in solid tumors.
• Analysis of complement system interactions with other biological cascades.

Main Results:

• The lectin pathway exhibits a dual role in various human solid tumors, including those of the female reproductive system, lung, and alimentary tract.
• Cross-talk with other enzyme-dependent cascades amplifies the complement system's influence but can also contribute to pathology.

Conclusions:

• The lectin pathway's complex role in cancer warrants further investigation.
• Targeting the lectin pathway's cross-talk mechanisms may offer novel therapeutic strategies for solid tumors.
