Enhancing Natural Killer and CD8 + T Cell-Mediated Anticancer Cytotoxicity and Proliferation of CD8 + T Cells with HLA-E Monospecific Monoclonal Antibodies [PDF]

, 2019
Cytotoxic NK/CD8+ T cells interact with MHC-I ligands on tumor cells through either activating or inhibiting receptors. One of the inhibitory receptors is CD94/NKG2A.

Reprogramming Antitumor Immunity: NK Cell Strategies to Navigate the Immunosuppressive Tumor Microenvironment

Advanced Science, EarlyView.
ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

Mature T‐cell leukemia/lymphoma with an NK‐like immunophenotype: A report of 7 cases

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Distinguishing T‐cell from NK‐cell neoplasms can occasionally be challenging, as neoplastic T cells can lose T‐cell markers such as surface CD3 (sCD3) and CD5 while acquiring NK‐cell markers such as CD16, CD56, and CD94. In this study, we present a series of 7 mature T‐cell lymphoma/leukemia cases with NK‐like immunophenotypes to clarify ...

NK cells in self-limited HCV infection exhibit a more extensively differentiated, but not memory-like, repertoire [PDF]

, 2017
Natural killer (NK) cells have long been thought of as a purely innate immune cell population, but increasing reports have described developmental and functional qualities of NK cells that are commonly associated with cells of the adaptive immune system.

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Natural Killer cells responsiveness to physical esercise: a brief review [PDF]

, 2013
Natural killer cells (NK) are a group of peripheral blood lymphocytes which display cytotoxic ac- tivity against a wide range of tumour cells. They are a consistent part of the inflammatory re- sponse that is activated when either internal or external ...

Inhibitory NKG2A+ and absent activating NKG2C+ NK cell responses are associated with the development of EBV+ lymphomas

Frontiers in Immunology, 2023
Epstein-Barr virus (EBV) is a ubiquitous herpesvirus, which infects over 90% of the adult human population worldwide. After primary infections, EBV is recurrently reactivating in most adult individuals.

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

British Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...

The role of neutrophils in the pathophysiology of inflammatory bowel diseases

Periodontology 2000, EarlyView.
Abstract Objectives Inflammatory bowel disease (IBD) encompasses a spectrum of chronic disorders of the gastrointestinal tract, with a potential bidirectional relationship with periodontitis. Neutrophils are key regulators of immune‐inflammatory responses and play a major role in both diseases.
