The mediators of the human stress response are commonly found within the hypothalamic-pituitary-adrenal (HPA) axis, and it is through this pathway where the body is coaxed back into homeostasis after exposure to stress (28). This axis is regulated through the synthesis and secretion of corticotropin-releasing factor (CRF) from the hypothalamus, which through a ligand-receptor interaction on the anterior pituitary gland, stimulates the release of adrenocorticotropic hormone (ACTH) into the systemic

The evidence in the literature suggests that the reproductive neuroendocrine axis is centrally regulated through inputs from kisspeptin-expressing neurons to GNRH-expressing neurons, which afterward regulate the release of LH and FSH from the anterior pituitary [Aki et al., 2015]. Kisspeptin primarily participates in the regulator of the reproductive axis performed its capability to operate upon, and evoke GNRH neurons, which have been shown to express GPR54 [d’Anglemont and Colledge, 2010].

understood. (1,3) . In histological assessments, both the myelin sheath and oligodendrocytes are damaged and attacked by cells of the immune system. Both, the humoural and cellular immune responses, are present. First a T cell phagocytic reaction by macrophages and targets the myelin sheath and oligodendrocytes. this is followed by the secretion of anti-myelin antibodies from B cells, opsonisation of the myelin sheath and activation of the complement cascade (1,3,4). There are several theories used

activation and infiltration of mononuclear cells predominantly antigen-specific CD4+ and CD8+ T cells and B cells in the CNS (Mosayebi et al., 2010, Zhang et al., 2014). Experimental autoimmune encephalomyelitis (EAE) is currently the most commonly used animal model for the study

Active innate immune response to bacterial infections Pathogen recognition Immunity depends on the recognition of pathogen components by innate receptors expressed on immune and non-immune cells against microbial pathogens. Innate receptors are conserved germ-line-encoded proteins and include TLRs (toll-like receptors), RLRs [RIG-1 like receptors (retinoic acid-inducible gene-1)] and NLRs (nod-like receptors). Receptors recognize pathogens or pathogen-derived products in different cellular compartments

bipolar cell subtype development Background: Mammalian retina is a highly organized tissue that represents the complexity of the central nervous system. Retinal bipolar cells are one of the major types of neuron that can be further divided into more than 10 subtypes. Both intrinsic and extrinsic cues are important for specifying these subtypes, but the contribution of extrinsic cues is less clear. Our preliminary data indicates that Shh is necessary and sufficient to promote cone bipolar cell fate

Basophil Activation Test (BAT) Basophils comprise <1 % of the circulating white blood cells, and they constitute a substrate for an important in vitro assay. Basophils express the high affinity IgE receptor and secrete cytokines and inflammatory mediators upon stimulation. Early studies of the role of basophils in allergic disease focused on the release of mediators, such as histamine and leukotrienes. The development of a flow cytometry based functional basophil assay became possible in 1991, when

sunlight expose which damage cells and cause apoptosis and the release of nuclear antigens. These stimuli begin a reaction that leads to distrupting to other cells in the body and exposure of their DNA, histones, and other proteins, particularly part of the cell nucleus. In individuals with lupus, both B-cells and T-cells become overactive. The two main consequences of this increased activity are the production of antibodies that recognize and destroy the body’s own cells and inflammation and can lead

monoclonal antibodies (mAbs) (BD Biosciences. Com, Pharmingen TM). The flow cytometry for the immune cells, EDTA treated blood was labeled with 10 µl monoclonal antibodies (mAbs) in 3 tubes. Tube 1 for T cell contained CD3-peridin chlorophyll protein (PerCP), CD4–fluorescein isothiocyanate (FITC) and CD8-phycoerythrin (PE). Tube 2 for NK cells contained CD16/CD56 PE and CD 3 FITC. Tube 3 for B cells contained CD19 FITC and CD22 PE (all Becton Dickson, San Jose, Calif). A non specific Isotype Control

eukaryotic cells. It is very interesting to also see that we are now able to genetically engineer mice with certain genes mysfucntioning to see the role that the gene plays in the whole upkeep of cellular homeostatis. IL-2 has been extensively studied by the scientific community because of its known involvement in the immune regulation. Provided that it has known functions of the immune system, it can also be inferred and tried to discuss that it is more complex than simply recruiting all the cells needed
