Proteasome inhibition induces apoptosis in primary human natural killer cells and suppresses NKp46-mediated cytotoxicity

open access: yesHaematologica, 2009
Background Bortezomib is a selective and potent inhibitor of the proteasome and has prominent effects in vitro and in vivo against tumors. Very recently, cytotoxic effects of bortezomib on immune-competent cells such as T cells and dendritic cells were ...

Tumor rejection by the poliovirus receptor family ligands of the DNAM-1(CD226) receptor [PDF]

open access: yes, 2006
The poliovirus receptor CD155 and its family member CD112 (nectin-2) are the ligands for the activating cell-surface receptor DNAM-1 on CD8(+) T cells and natural killer (NK) cells. Here, we demonstrate that, whereas the RMA tumor grew in syngeneic mice,

Marked Long‐term Improvement in Lung Function in Melanoma Differentiation‐associated Protein 5 (MDA5) Antibody Positive Dermatomyositis Patients: Experience of a Single Center Longitudinal Cohort in North America

open access: yesArthritis Care &Research, Accepted Article.
Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation‐associated gene 5 antibody (MDA5 ab) associated dermatomyositis (DM). Methods Thirty patients with MDA5 ab DM were identified in a single center longitudinal cohort of 352 patients with ...

Natural killer cell-derived exosome-based cancer therapy: from biological roles to clinical significance and implications

open access: yesMolecular Cancer
Natural killer (NK) cells are important immune cells in the organism and are the third major type of lymphocytes besides T cells and B cells, which play an important function in cancer therapy.

Recognition of microbial glycolipids by Natural Killer T cells

open access: yesFrontiers in Immunology, 2015
T cells can recognize microbial antigens when presented by dedicated antigen-presenting molecules. While peptides are presented by classical members of the Major Histocompatibility (MHC) family (MHC I and II), lipids, glycolipids and lipopeptides can be ...

Host‐Directed Biomaterials for Combatting Bloodstream Infections: From Macrocyclic Peptides to Immune‐Activating Cell Backpacks

open access: yesAdvanced Functional Materials, EarlyView.
Bloodstream infections (BSI) are one of the leading causes of mortality and morbidity in both civilian and military populations. This paper summarizes recent progress in novel treatment strategies to manage BSI arising from both bacterial and fungal pathogens using molecules, particles, and materials to elicit host‐directed immunity.

Natural Killer Cells Suppress T Cell-Associated Tumor Immune Evasion

open access: yesCell Reports, 2019
Summary: Despite the clinical success of cancer immunotherapies, the majority of patients fail to respond or develop resistance through disruption of pathways that promote neo-antigen presentation on MHC I molecules.

Natural killer T cells in pulmonary disorders

open access: yesRespiratory Medicine, 2011
Natural killer T (NKT) cells, a unique subgroup of lymphocytes with features of both T and natural killer (NK) cells, represent a bridge between innate and adaptive immunity. They have the ability to either promote or suppress immune responses. With these immunoregulatory functions, NKT cells have emerged as an important subset of lymphocytes with a ...
