The most common adverse event following allogeneic hematopoietic stem cell transplantation (HSCT) is graft-versus-host disease (GVHD), which can increase morbidity and mortality in HSCT patients. (oncologynurseadvisor.com)
An environment for GVHD is formed when antigen-presenting cells are activated by the patient's disease and the pretreatment destruction of cells caused by chemotherapy and radiotherapy. (oncologynurseadvisor.com)
Diagnosis of GVHD is difficult because of its broad presentation that may manifest similar to other conditions such as drug reactions and viral infections. (oncologynurseadvisor.com)
Successful outcome following hematopoietic stem cell transplantation (HSCT) is ultimately determined by the ability to achieve sustained engraftment and immune reconstitution, control of graft-versus-host disease (GVHD), and in patients with hematological malignancy the complete eradication of abnormal or malignant cells.

Two main advantages of BCMA as an antigen for CAR-T therapy are the potential reduction of on-target/off-tumor toxicity and the lack of antigen-dependent reduction in CAR-T cell expansion [ 16 ]. (biomedcentral.com)

An immune response is a physiological reaction which occurs within an organism in the context of inflammation for the purpose of defending against exogenous factors. (wikipedia.org)
In general, there are two branches of the immune response, the innate and the adaptive, which work together to protect against pathogens. (wikipedia.org)
This is so that in the case that an exposure to the real pathogen occurs, the body can rely on the secondary immune response to quickly defend against it. (wikipedia.org)
It is becoming evident that both the innate and the adaptive immune response are involved in the pathogenesis of autoimmune diseases ( 4 ), especially adaptive immune response. (frontiersin.org)

These include a wide variety of different toxins, viruses, intra- and extracellular bacteria, protozoa, helminths, and fungi which could cause serious problems to the health of the host organism if not cleared from the body. (wikipedia.org)
Inflammation is a protective attempt by the organism to remove the injurious stimuli and to initiate the healing process. (absoluteastronomy.com)

Peptic ulcer disease can also be due to Helicobacter pylori infection, the incidence of which is increased in PV, while the pruritus associated with this disorder may be a consequence of mast cell activation by JAK2 V617F. (basicmedicalkey.com)
However, to this day, in the fight against virus infection, there is no real winner. (medsci.org)
Pneumonia caused by the SARS-CoV-2 is spreading continuously, the ability to adapt host and genomic mutation of Coronavirus (CoV) lead to hampering in treatment or control of the infection. (medsci.org)
There may be findings that are unrelated to cervical cancer, such as signs of infection with yeast, herpes, or Trichomonas vaginalis (a type of sexually transmitted disease), for example. (com.ng)

Findings: We all demonstrated that dependable recognition associated with differentially depicted transcripts inside undissected user interface place with the parasite-host organization is feasible and also helpful when it comes to differential-expression patterns.Pilocarpine-induced epileptic point out (Position epilepticus) creates a good aberrant growing LGK-974 supplier regarding hippocampal mossy fibers, which usually affect the intrahippocampal build.

Three top experts on HHV-6A/B teamed up to write a comprehensive review and propose criteria for establishing HHV-6A/B to MS, epilepsy and Alzheimer's disease. (hhv-6foundation.org)
Previously I have written about the roles of glia and microglia in Alzheimer's disease and in spinal cord injury. (anti-agingfirewalls.com)
In my February 2010 blog entry New views of Alzheimer's disease and new approaches to treating it , I cited evidence for the hypothesis that microglial cell senescence is probably a fundamental cause for AD, a cause upstream of beta amyloid plaque production and the setting in of tau tangles. (anti-agingfirewalls.com)
In the March 2011 blog entry Alzheimer's Disease Update I included a discussion on this hypothesis and on how with aging microglia lose their capability to get rid of beta amyloid via phagocytosis. (anti-agingfirewalls.com)

Five patients had progressive disease, two patients had stable disease, and one patient experienced a partial response after receiving donor lymphocyte infusions and IFN-α. (aacrjournals.org)
CD8 + CTL clones recognizing minor H antigens were isolated from five patients studied. (aacrjournals.org)
Among these 132 patients, 8 liver cancer patients and 10 lung cancer patients who received ≥5 cell infusions showed greatly prolonged survival, which preliminarily verified the efficacy of allogeneic Vγ9Vδ2 T-cell therapy. (nature.com)
The use of salicylates as a tonic against thrombosis in PV patients is not only potentially harmful if the red cell mass is not controlled by phlebotomy, but is also an unproven remedy. (basicmedicalkey.com)
La réanimation agressive, la prise en charge nutritionnelle, l'excision chirur- gicale complète des plaies infectées, la fermeture rapide des plaies, les greffes et la mise au point d'une chimiothérapie locale et systémique efficace ont permis d'améliorer grandement le taux de morbidité et de mortalité chez les patients brûlés. (who.int)
Patients diagnosed with GB have a dismal prognosis, and typically succumb to the disease within 3 months if untreated. (frontiersin.org)
however, 70% to 80% of patients with HCV go on to develop chronic liver disease during a prolonged period of up to 40 years, and up to 50% of them may remain relatively asymptomatic during that time. (thedoctorsdoctor.com)
Although all patients were seropositive for HCV RNA at the time of biopsy, we were unable to detect HCV RNA by reverse-transcription polymerase chain reaction in any of the patients. (thedoctorsdoctor.com)
Patients were subsequently treated with disease modifying antirheumatic drugs (usually methotrexate, sulphasalazine, or a combination of both). (exposed-skin-care.net)
