  • rbf1 , the Drosophila homolog of Rb , also displays a pro- apoptotic activity in proliferative cells. (sdbonline.org)
  • Diffuse large B cell lymphoma (DLBCL) represents the most frequent form of non-Hodgkin's lymphoma (NHL). (frontiersin.org)
  • The first parameter to assess is cell number and morphology. (dvm360.com)
  • Over lifetime, due to the action of several stressors such as DNA damage and telomere shortening, senescent cells accumulate in the organism and release a variety of pro-inflammatory cytokines responsible for low-grade inflammation. (frontiersin.org)
  • Infection with Giardia results in decreased expression of brush border enzymes, morphological changes to the microvillus, increased intestinal permeability, and programmed cell death of small intestinal epithelial cells. (wikipedia.org)
  • Background Anti(α)-programmed cell death-1 (PD-1)/programmed death-ligand 1 (PD-L1) monotherapy fails to provide durable clinical benefit for most patients with carcinoma. (bmj.com)
  • First, γδ T cells exposed to complicated cytokine networks are potentially affected by multiple inhibitory mechanisms. (explorationpub.com)
  • HIV uptake by DCs is unique in that it does not preferentially drive DC maturation and stimulate T cell instruction, but rather favors viral spread [10]. (jscimedcentral.com)
  • Griscelli syndrome type 2 is caused by a defect in the RAB27A gene, which affects a melanosome-anchoring complex in melanocytes, affecting release of cytolytic granules from T cells and natural killer cells. (medscape.com)
  • For example, a dog that has a high neutrophil count and evidence of a bacterial infection that recurs after antibiotic withdrawal may have a neutrophil defect (such as inability to phagocytose and kill). (dvm360.com)
  • In contrast, a dog with chronic fungal infection would be more likely to have a T cell defect. (dvm360.com)
  • RAG1 and RAG2 cause a defect in the variable diversity joining (VDJ) rearrangement needed for mature T and B cells to develop. (medscape.com)
  • Recognize that patients with short-limbed skeletal dysplasia with cartilage-hair hypoplasia can also have either a T-cell or combined defect. (medscape.com)
  • Those diseases are discussed in T-Cell Disorders. (medscape.com)
  • In other B-cell and T-cell disorders, additional anomalies may predominate, and clinical manifestations suggestive of immunodeficiency may occur late in life. (medscape.com)
