NK cells as effectors of acquired immune responses: effector CD4+ T cell-dependent activation of NK cells following vaccination.
We characterized vaccine-induced cellular responses to rabies virus in naive adult volunteers. Contrary to current paradigms, we observed potent and prolonged in vitro NK cell cytokine production and degranulation responses after restimulation of PBMCs with inactivated rabies virus in vaccinated, but not in unvaccinated, individuals. This "recall" NK cell response was absolutely dependent on Ag...
متن کاملImaging Case: NK/T-Cell Lymphoma, Nasal Type
Peripheral T-cell lymphomas are a group of heterogeneous disorders and according to WHO classification, are categorized into nodal and extranodal forms. NK/T-cell lymphoma, nasal type, is a subtype of extranodal peripheral T-cell lymphoma and commonly presents as a midfacial destructive lesion. This disorder is more prevalent in Asia and South America and has a strong association with Epstein B...
متن کاملExtranodal NK/T Cell Lymphoma with Destruction of the Uvulae: A Case Report
Introduction: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. Case Report: The present study examines a case o...
متن کاملToward a prime-boost regime for NK cells?
In this issue of Blood, Romee et al report a novel strategy for triggering memorylike NK-cell responses with implications for NK cell–based immunotherapy.1 A lthough natural killer (NK) cells were identified more than 30 years ago based on their ability to kill tumor cells in the absence of prior sensitization, we have only recently begun to explore their potential in clinical therapies against...
متن کاملCD26+ Cord Blood Mononuclear Cells Significantly Produce B, T, and NK Cells
Background: Umbilical cord blood (UCB) is an alternative source of hematopoietic stem cell transplantation (HSCT), used in Leukemia treatment. CD26+ cells, a fraction of CD34 positive cells, are a major population of UCB cells which negatively regulate the in vivo homing and engraftment of HSCs. CD26 is highly expressed in various cells such as HSCs, immune cells, fibroblasts, and epithelial ce...
