Disease relevance of IL1A

  • Sequences encoding mature bovine IL-1 alpha and IL-1 beta were inserted into E. coli expression plasmids and biologically active proteins were synthesized as judged by the ability of the recombinant proteins to induce proliferation of bovine thymocytes [1].
  • No disruption of the BBB occurred for up to 2 h after the i.v. injection of 2 micrograms/mouse of IL-2 (10(5) U/kg of body weight), 2 micrograms of IL-1 alpha (10(7) U/kg), or 2 micrograms of IL-1 beta (10(7) U/kg) [2].
  • Intraglomerular expressions of IL-1 alpha and platelet-derived growth factor (PDGF-B) mRNA in experimental immune complex-mediated glomerulonephritis [3].
  • In this study we investigated intraglomerular expressions of PDGF-B and IL-1 alpha mRNA in mice with bovine serum albumin (BSA) nephritis, a model of immune complex-mediated glomerulonephritis, using the reverse transcription-polymerase chain reaction (RT-PCR) method [3].
  • From these studies, we conclude that TNF and IL-1 alpha directly increase vascular endothelial cell permeability in vitro and speculate that these cytokines may be involved in the acute vascular endothelial injury associated with endotoxic shock [4].
 

High impact information on IL1A

 

Biological context of IL1A

  • The results indicated that PAX8 as well as interleukin beta and interleukin alpha (IL1B and IL1A) genes detected on the human chromosome segment HSA 2q13-->q21 maintain a similar order and location in these three related species [9].
  • 3. The genes for IL1A and IL1B were both assigned to Chromosome (Chr) 3, in the region q1.2-->q1.3 and q1.1-->q1.4, respectively [10].
  • TNF alpha also demonstrated a neuropeptide-specific pattern of modulation of second-messenger effects on chromaffin cell neuropeptide levels similar to those seen with IL-1 alpha [11].
 

Anatomical context of IL1A

 

Associations of IL1A with chemical compounds

  • Poly (A) + RNAs isolated from PBMCs by guanidium thiocyanate/oligo (dT)-cellulose chromatography extraction, were reverse-transcribed and the complementary DNAs amplified in a polymerase chain reaction primed with bovine IL-1 alpha and IL-1 beta sequence-specific primers [16].
  • As a result of the amplification of specific cDNAs by 35 cycles of PCR, the IL-1 alpha mRNA was detected from 0.01 ng of poly (A) + RNA, and IL-1 beta mRNA was detected from 0.1 pg of poly (A) + RNA isolated from PBMCs stimulated with lipopolysaccharide (LPS) for 4 h [16].
  • The presence of a Factor Xa cleavage site in the IL-1 alpha proprotein suggests that Factor Xa may be involved in the processing of ovine IL-1 alpha to its mature form [17].
  • IL-1 alpha and IL-1 beta stimulated a time (0-72 hr) and concentration-dependent (0.01-10 ng/ml) production of collagenase, gelatinase, caseinase, and prostaglandin E2 (PGE2) in BNC monolayer cultures [18].
  • Stimulation of VIP and substance P biosynthesis by forskolin was markedly enhanced by IL-1 alpha, while forskolin stimulation of enkephalin and neurotensin biosynthesis was unaffected [11].
 

Other interactions of IL1A

  • There was an early increase in transcripts for genes encoding proinflammatory mediators (IFNG, IL1A, TNF, and IL12) in N'Dama by 14 days postinfection (dpi) compared with preinfection levels that was not detected in the susceptible Boran breed [19].
  • TREATMENT: Fibronectin fragments or IL-1 alpha, which potently cause proteoglycan (PG) loss from cartilage, were added to cultures also containing the catabolism-blocking agents: insulin-like growth factor-1, or N-acetylcysteine, or Arg-Gly-Asp-Ser peptide, and the effects of these agents on blocking PG loss determined [20].
