Iba1 (Ionized calcium-binding adapter molecule 1; allograft inflammatory factor 1, AIF1) is a prominent microglial marker extensively used in neuroscience research. Its expression increases in various neurodegenerative conditions, including Alzheimer's disease (AD), indicating microglial activation and neuroinflammation. Researchers utilize Iba1 in stainings to assess microglial response and activity in different models, making it essential for understanding inflammatory processes in the brain. Changes in Iba1 expression provide valuable insights into neuroinflammation, highlighting its importance in studying diseases like AD.

The Iba1 antibody (ab5076) is commonly used as a marker of microglia activation in staining and immunohistochemistry, given that ionized calcium binding adaptor molecule 1 (Iba1) is a microglia/macrophage-specific calcium-binding protein with actin-bundling activity that participates in membrane ruffling and phagocytosis in activated microglia.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

Iba1 also known as allograft inflammatory factor 1 (AIF1) is a protein with a molecular weight of approximately 17 kDa. It is widely expressed in microglia which are the resident immune cells of the central nervous system (CNS). Iba1 plays a mechanical role in actin-binding and modulating cytoskeleton dynamics which affects cell shape and motility. It is also found in other myeloid-derived cells including macrophages and monocytes where it influences cellular processes linked to inflammation and immune responses.
Biological function summary

The involvement of Iba1 in actin polymerization impacts microglia's ability to perform phagocytosis and cytokine production. Iba1 does not appear to be part of any large protein complex but interacts directly with actin filaments to facilitate cytoskeletal reorganization. This function enables the cells to move and respond efficiently to tissue damage or pathogens in the CNS. It plays an important role in supporting cellular changes associated with immune surveillance and neuroinflammatory responses.

Pathways

Microglial activation relies heavily on Iba1 for executing acts linked with neuroinflammation. Iba1 engages in the NF-kB signaling pathway significant in managing inflammatory responses. It interacts with proteins such as MyD88 and IRAK4 which aid in transmitting signals from toll-like receptors. These pathways enable changes in gene expression critical for microglial response to various stimuli. Furthermore Iba1 also contributes to the PI3K/Akt pathway where it influences cell survival and proliferation interacting with proteins like Akt1 and PTEN.

Iba1 has implications in neurodegenerative diseases notably Alzheimer's disease and multiple sclerosis. In Alzheimer's disease increased expression of Iba1 is observed in activated microglia around amyloid plaques suggesting a role in plaque clearance and neuroinflammation. The protein relates to amyloid precursor protein (APP) as microglia respond to abnormal accumulations. In multiple sclerosis Iba1 expression marks activated microglia involved in demyelination processes where it associates with proteins like myelin basic protein (MBP) highlighting its role in the disease's pathology.
