Western blot - Anti-MICA + MICB antibody [EPR22031] (AB224702)

Western blot : Anti-MICA antibody [EPR22031] (ab224702) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab224702 was shown to bind specifically to MICA. A band was observed at 43 kDa in wild-type A549 cell lysates with no signal observed at this size in MICA knockout cell line. To generate this image, wild-type and MICA knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Supplementary information

MICA and MICB also known as MIC-A and MIC-B are stress-induced proteins with significant roles in immune responses. These proteins are widely known for their presence on the surface of many human cell types most notably epithelial and endothelial cells. MICA is a glycoprotein with a molecular mass of approximately 70 kDa while MICB has a similar structure and mass. They are both part of the MHC class I-like molecules and function as ligands to the NKG2D receptor on natural killer (NK) cells and certain T cells a critical interaction for immune surveillance.
Biological function summary

MICA and MICB act in the activation of the immune system by modulating NK cells and CD8+ T cell activities. These proteins do not form part of a complex but operate independently to signal the presence of infected or transformed cells to the immune system. They often appear on the cell surface under stress such as during viral infections or cancerous transformations activating immune cells to target and destroy these abnormal cells.

Pathways

The MICA/MICB interaction with NKG2D is integral to the immune checkpoint pathway. This pathway plays a significant role in regulating the immune system's response to aberrant cells. Additionally MICA and MICB activity is linked to the regulation of the cytokine IFN-γ promoting the recruitment and activation of immune effector cells. The roles of these proteins in these pathways underline their importance in maintaining immune homeostasis and responding to pathological challenges.

MICA and MICB have notable associations with cancer and autoimmune diseases. Aberrant expression of these proteins on tumor cells facilitates their recognition and elimination by immune cells linking MICA and MICB directly to tumor immunosurveillance. In autoimmune disorders improper regulation of MICA/MICB expression can lead to undesirable immune cell activation contributing to conditions like rheumatoid arthritis. The proteins connect with others like NKG2D in both cancer immunity and autoimmune diseases highlighting their dual role in health and disease.

Target data

Widely expressed membrane-bound protein which acts as a ligand to stimulate an activating receptor KLRK1/NKG2D, expressed on the surface of essentially all human natural killer (NK), gammadelta T and CD8 alphabeta T-cells (PubMed : 11491531, PubMed : 11777960). Up-regulated in stressed conditions, such as viral and bacterial infections or DNA damage response, serves as signal of cellular stress, and engagement of KLRK1/NKG2D by MICA triggers NK-cells resulting in a range of immune effector functions, such as cytotoxicity and cytokine production (PubMed : 10426993).
