Hemorrhagic cystitis may be induced by infection, radiation therapy, medications, or may be idiopathic. Along with hemorrhagic features, symptoms include urinary urgency and frequency, dysuria (painful urination) and visceral pain. Cystitis-induced visceral pain is one of the most challenging types of pain to treat and an effective treatment would...
Stem cell technology can allow us to produce human neuronal cell types outside the body, but what exactly are stem cells, and what challenges are associated with their use? Stem cells are a kind of cell that has the capacity to self-renew to produce additional stem cells by mitosis, and also to differentiate into other – more mature – cell types. S...
Neuromyelitis optica spectrum disorders (NMOSD) are rare, debilitating autoimmune diseases of the central nervous system. Many NMOSD patients have antibodies to Aquaporin-4 (AQP4). Prior studies show associations of NMOSD with individual Human Leukocyte Antigen (HLA) alleles and with mutations in the complement pathway and potassium channels. HLA a...

Background
Dendritic cells (DC) induce adaptive responses against foreign antigens, and play an essential role in maintaining peripheral tolerance to self-antigens. Therefore they are involved in preventing fatal autoimmunity. Selective delivery of antigens to immature DC via the endocytic DEC-205 receptor on their surface promotes antigen-specific...
Significance
Certain large neurons deep in the brainstem, in the nucleus gigantocellularis (NGC), are crucial for waking up the brain from deep sleep, anesthesia, or injury. NGC neurons, which project axons to central thalamus, should be especially important because central thalamic stimulation heightens CNS arousal in animals and in human patients...

Background:
The cleavage-stage mouse embryo is composed of superficially equivalent blastomeres that will generate both the embryonic inner cell mass (ICM) and the supportive trophectoderm (TE). However, it remains unsettled whether the contribution of each blastomere to these two lineages can be accounted for by chance. Addressing the question of...
Dendritic cells (DCs) and Foxp3-expressing CD4(+) regulatory T (Treg) cells play non-redundant roles in the maintenance of peripheral tolerance to self-antigens, thereby preventing fatal autoimmunity. A common hallmark of intra- and extra-thymic Treg cell lineage commitment is the induction of Foxp3 expression as a consequence of appropriate T cell...
NK cells eliminate cancer and virus-infected cells through their cytolytic activity. The last step in NK-cell cytotoxicity, resulting in exocytosis of granule content, requires fusion of lytic granules with the plasma membrane. Proteins from the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) family mediate membrane fu...
The major focus of this paper is to describe and evaluate current information on the role of natural killer cells (NK cells) in the pathogenesis of blistering diseases.
