CARD-BCL-10-MALT1 signalling in protective and pathological immunity

Area of Science:

• Immunology
• Molecular Biology
• Cell Signaling

Background:

• CARD protein-BCL-10-MALT1 (CBM) signalosomes are crucial multiprotein platforms controlling immune and inflammatory pathways.
• These complexes are essential for host defense and maintaining tissue homeostasis.
• Genetic alterations in CBM signaling components are implicated in various immune-mediated diseases.

Purpose of the Study:

• To review the regulation and signaling mechanisms of CBM complexes.
• To discuss the physiological roles of CBM signaling in host defense and homeostasis.
• To explore the pathophysiological functions of CBM complexes in immune-related diseases and cancers.

Main Methods:

• Literature review of CBM signalosome function.
• Analysis of CBM complex assembly and protease activity.
• Examination of CBM signaling in immune and inflammatory contexts.

Main Results:

• CBM signalosomes form self-organizing filaments upon immune activation.
• CBM complexes regulate canonical nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) pathways.
• Two layers of inflammatory gene expression control are mediated by CBM signaling, including mRNA-binding protein degradation.

Conclusions:

• CBM signalosomes play a vital role in immune regulation and tissue homeostasis.
• Understanding CBM signaling is critical for addressing immune deficiencies, inflammatory disorders, and lymphoid malignancies.
• Further research into CBM complexes may reveal therapeutic targets for immune-mediated diseases.
