  • 功能Potent proinflammatory cytokine. Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production. Promotes Th17 differentiation of T-cells.
  • 组织特异性Expressed in activated monocytes/macrophages (at protein level).
  • 序列相似性Belongs to the IL-1 family.
  • 翻译后修饰Activation of the IL1B precursor involves a CASP1-catalyzed proteolytic cleavage. Processing and secretion are temporarily associated.
  • 细胞定位Cytoplasm, cytosol. Lysosome. Secreted, exosome. Cytoplasmic vesicle, autophagosome. Secreted. The precursor is cytosolic. In response to inflammasome-activating signals, such as ATP for NLRP3 inflammasome or bacterial flagellin for NLRC4 inflammasome, cleaved and secreted. IL1B lacks any known signal sequence and the pathway(s) of its secretion is(are) not yet fully understood (PubMed:24201029). On the basis of experimental results, several unconventional secretion mechanisms have been proposed. 1. Secretion via secretory lysosomes: a fraction of CASP1 and IL1B precursor may be incorporated, by a yet undefined mechanism, into secretory lysosomes that undergo Ca(2+)-dependent exocytosis with release of mature IL1B (PubMed:15192144). 2. Secretory autophagy: IL1B-containing autophagosomes may fuse with endosomes or multivesicular bodies (MVBs) and then merge with the plasma membrane releasing soluble IL1B or IL1B-containing exosomes (PubMed:24201029). However, autophagy impacts IL1B production at several levels and its role in secretion is still controversial. 3. Secretion via exosomes: ATP-activation of P2RX7 leads to the formation of MVBs containing exosomes with entrapped IL1B, CASP1 and other inflammasome components. These MVBs undergo exocytosis with the release of exosomes. The release of soluble IL1B occurs after the lysis of exosome membranes (By similarity). 4. Secretion by microvesicle shedding: activation of the ATP receptor P2RX7 may induce an immediate shedding of membrane-derived microvesicles containing IL1B and possibly inflammasome components. The cytokine is then released in the extracellular compartment after microvesicle lysis (PubMed:11728343). 5. Release by translocation through permeabilized plasma membrane. This may occur in cells undergoing pyroptosis due to sustained activation of the inflammasome (By similarity). These mechanisms may not be not mutually exclusive.

  • ab8320 staining IL1 beta in lung inflammatory cells from Rhesus monkey by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with formaldehyde, permeabilized with Tween 20 and blocked with 10% serum for 2 hours at 21°C. Samples were incubated with primary antibody (1/25 in PBS + 10% serum + 1% Tween 20) for 18 hour at 4°C. An diluted Alexa Fluor®594-conjugated + 1.4nm Goat anti-mouse IgG polyclonal was used as the secondary antibody.

  • Immunohistochemical analysis of frozen Human skin tissue taken from patients with localized cutaneous leishmaniasis (A, C), diffuse cutaneous leishmaniasis (E). Normal tissue (G) was used as a negative control.

    IL1 beta was stained using ab8320 at 1/100 dilution for 1 hour at room temperature. ab94705 Mouse and Rabbit Specific HRP/AEC Detection IHC Kit was used to detect staining. Hematoxylin was used as a counterstain.

I am glad that the Rhesus tissue worked well! Unfortunately the homology for ab8320 with sheep is only 60%, to low for any reactivity. Another IL1-beta antibody, ab45692 does have 88% homology but has only been tested for Western Blot. Please let me kn...
