Interleukin 6 (IL-6) is a multifunctional 24 kDa protein originally discovered in the medium of RNA stimulated fibroblastoid cells. It is upregulated by IL1, TNF, PDGF, IFN beta, TNF alpha, NGF, IL17 and downregulated by glucocorticoids IL4, TGF beta. IL-6 appears to be directly involved in the responses that occur after infection and cellular injury, and it may prove to be as important as IL1 and TNF alpha in regulating the acute phase response. IL-6 has also been implicated in regulating adipose mass.

Description:
Ten to forty percent of the patients with acquired immunodeficiency syndrome (AIDS) develop cytomegalovirus (CMV) infections. In some patients with AIDS, cytomegalovirus is detected in the bronchoalveolar lavage fluid (BALF), urine, and other specimens, even when there are no symptoms of cytomegalovirus disease. An indicator of active CMV infection is needed to facilitate the diagnosis of cytomegalovirus disease in patients with AIDS or HIV infection. Cytomegalovirus p65 antigen was detected in the leukocytes of both the peripheral blood and BALF during the early phase of CMV disease.

Description:
CD4 is a membrane glycoprotein of T lymphocytes that interacts with major histocompatibility complex class II antigens and is also a receptor for the human immunodeficiency virus. This protein is expressed not only in T lymphocytes, but also in B cells, macrophages, and granulocytes. It is also expressed in specific regions of the brain. The protein functions to initiate or augment the early phase of T-cell activation, and may function as an important mediator of indirect neuronal damage in infectious and immune-mediated diseases of the central nervous system. Multiple alternatively spliced transcript variants encoding different isoforms have been identified.

Description:
Progesterone receptors (PRs) are nuclear hormone receptors of the NR3C class, which also includes mineralocorticoid, glucocorticoid and androgen receptors. They exist as homodimers coupled to Hsp90 or HMGB proteins, which are shed upon activation. The major signaling pathway used by progesterone receptors is via direct DNA binding and transcriptional regulation of target genes. They can also signal by binding to other proteins, mainly with transcription factors such as NF-κB, AP-1 or STAT. Progesterone receptors are found in the female reproductive tract, mammary glands, brain and pituitary gland and receptor expression is induced by estrogen. Well established functions of progesterone receptors include ovulation, implantation, mammary gland development and maintenance of pregnancy. In addition, progesterone, signaling through the progesterone receptor, increases the ventilatory response of the respiratory centers to carbon dioxide and decreases arterial and alveolar PCO2 in the luteal phase of the menstrual cycle and during pregnancy. The human gene encoding the progesterone receptor has been localized to 11q22.

Description:
Caspase 14 (CASP14) is an enzyme that belongs to the peptidase C14A family. The Caspase 14 protein is complexed of unprocessed caspase-14 and processed 19 kDa (p19) and 10 kDa (p10) subunits. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes, which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerise to form the active enzyme. CASP14 has been shown to be processed and activated by Caspase 8 and Caspase 10 in vitro, and by anti-Fas agonist antibody or TNF-related apoptosis inducing ligand in vivo. The expression and processing of this caspase may be involved in keratinocyte terminal differentiation, which is important for the formation of the skin barrier. It is believed to be a non-apoptotic caspase which is involved in epidermal differentiation, keratinocyte differentiation and cornification. CASP14 probably regulates maturation of the epidermis by proteolytically processing filaggrin.

Description:
p21WAF1 is a specific inhibitor of cdk s and a tumor suppressor involved in the pathogenesis of a variety of malignancies. The expression of this gene acts as an inhibitor of the cell cycle during G1 phase and is tightly controlled by the tumor suppressor protein p53. Its expression is induced by the wild type, but not mutant, p53 suppressor protein. Normal cells generally display a rather intense nuclear p21 expression. Loss of p21 expression has been reported in many carcinomas (gastric carcinoma, non-small cell lung carcinoma, thyroid carcinoma).

Description:
Système de surveillance de l'évacuation d'air en option avec ventilateur:
Pour une ventilation et une surveillance plus facile de l'ensemble du système d'aération des armoires de sécurité. Un capteur surveille la vitesse/le flux du débit d'air et émet un signal visuel et sonore si la valeur passe en dessous de la valeur de consigne. L'unité complète de surveillance de l'évacuation est fournie pré-montée (prête à être raccordée) et placée directement dans l'armoire. La valeur de consigne du débit de flux d'air est prédéfinie en usine et peut être réglée indépendamment via une prise de contrôle de la différence de pression. Le débit volumétrique ainsi que l'alimentation électrique sont également contrôlés. Le système inclut deux contacts flottants (24 V/2 A) pour la transmission du signal vers une salle de commande externe. L'accumulateur de stockage interne alimente les systèmes de surveillance pour une durée de 4 heures en cas de coupure de courant, offre une indication claire des défaillances et permet une surveillance permanente et conforme DIN EN 1946-7. La cage est composée d'une tôle d'acier pulvérisé, couleur perle argentée.
