This case report describes a very rare and highly malignant type of lymphoma, which presents as a mucous cyst on the finger. The cyst was excised and the specimen pathohistologically analyzed. The analysis revealed the presence of a Natural-Killer cell neoplasm. This case illustrates and stresses the importance of a pathohistological examination when doubts arise about the initial diagnosis of a benign tumorous lesion.

Cancer immunotherapy using engineered cytotoxic effector cells has demonstrated significant potential. The limited spatial complexity of existing models, however, poses a challenge to mechanistic studies attempting to approve existing approaches of effector cell-mediated cytotoxicity within a three-dimensional, solid tumor-like environment. To gain additional experimental control, we developed an approach for constructing three-dimensional (3D) culture models using smart polymers that form temperature responsive hydrogels.

Immune cells determine the role of the tumor microenvironment during tumor progression, either suppressing tumor formation or promoting tumorigenesis. We analyzed the profile of immune cells in the tumor microenvironment of control mouse skins and skin tumors at the single-cell level. We identified 15 CD45 immune cell clusters, which broadly represent the most functionally characterized immune cell types including macrophages, Langerhans cells (LC), conventional type 1 dendritic cells (cDC1), conventional type 2 dendritic cells (cDC2), migratory/mature dendritic cells (mDC), dendritic epidermal T cells (DETC), dermal γδ T cells (γδT), T cells, regulatory T cells (Tregs), natural killer cells (NK), type 2 innate lymphoid cells (ILC2), neutrophils (Neu), mast cells (Mast), and two proliferating populations (Prolif.

Cancer is a condition that has been with us for centuries; however, the therapies that have been developed are often associated with significant toxicity and various side effects. Recent advances in immunology have revealed the potential of the immune system to fight cancer, leading to the emergence of immunotherapy. This review focuses on Natural Killer (NK) cells, innate immune effectors with a remarkable ability to directly kill cancer cells.

Acute myeloid leukemia (AML) that is relapsed and/or refractory post-allogeneic hematopoietic cell transplantation (HCT) is usually fatal. In a prior study, we demonstrated that AML relapse in high-risk patients was prevented by post-HCT immunotherapy with Epstein-Barr virus (EBV)-specific donor CD8 T cells engineered to express a high-affinity Wilms Tumor Antigen 1 (WT1)-specific T-cell receptor (TTCR- C4). However, in the present study, infusion of EBV- or Cytomegalovirus (CMV)-specific T did not clearly improve outcomes in fifteen patients with active disease post-HCT.

Glucose oxidase (GOX)-induced starvation is a safe treatment for tumor. However, the non-specific targeting of GOX and the plasticity of tumor metabolism lead to toxic side effects and low tumor mortality. Thus, it is necessary to develop a synergistic strategy with high tumor targeting specificity to enhance the mortality of GOX.
