Function

Cytokine that binds to TNFRSF3/LTBR. Binding to the decoy receptor TNFRSF6B modulates its effects. Acts as a ligand for TNFRSF14/HVEM (PubMed:10754304, PubMed:9462508). Upon binding to TNFRSF14/HVEM, delivers costimulatory signals to T cells, leading to T cell proliferation and IFNG production (PubMed:10754304).

Activity summary

LIGHT also known as TNFSF14 is a member of the tumor necrosis factor (TNF) superfamily. It has an approximate mass of 24 kDa. You can find LIGHT expressed in various tissues including lymphoid tissues such as the spleen and lymph nodes. LIGHT serves as a ligand that can bind to receptors like lymphotoxin beta receptor (LTβR) and herpesvirus entry mediator (HVEM). Researchers have studied "mouse LIGHT" and "LIGHT protein" to understand its role in immune regulation. Additionally the term "anti-LIGHT" often refers to tools like antibodies used to investigate or inhibit LIGHT's activity.

Biological function summary

LIGHT plays a role in regulating immune responses and inflammation. It is part of a complex formed when it binds to its receptors influencing the proliferation and survival of immune cells such as T cells. LIGHT's interaction with HVEM can modulate T cell signaling cytokine production and dendritic cell maturation. It contributes to the organization of secondary lymphoid organs impacting immune surveillance and homeostasis. The presence of "APC LIGHT" indicates its involvement in antigen-presenting cell activities essential for adaptive immunity.

Pathways

LIGHT operates within the TNF receptor superfamily signaling pathway. This pathway involves other TNF members like TNF-α and lymphotoxin alfa which can also interact with LTβR. Another relevant pathway is the NF-kB signaling cascade which LIGHT activation can trigger. This cascade regulates gene expression related to immune response and cell survival. In connection to these pathways LIGHT's interaction with proteins like HVEM and LTβR helps maintain immune system balance.

Associated diseases and disorders

LIGHT has links to autoimmune diseases and cancer. Abnormal LIGHT signaling can contribute to conditions like rheumatoid arthritis where immune cell regulation becomes dysregulated. In cancer LIGHT may play a dual role by promoting tumor immunity or conversely tumor progression depending on the context of its expression and receptor interaction. The LIGHT interaction network includes TNFRSF members and can influence pathological inflammatory responses when disrupted.
