NK Cell Effector Functions Regulation by Modulating nTreg Cell Population During Progressive Growth of Dalton's Lymphoma in Mice.

NK Cell Effector Functions Regulation by Modulating nTreg Cell Population During Progressive Growth of Dalton's Lymphoma in Mice. Immunol Invest. 2017 Sep 11;:1-17 Authors: Tomar MS, Kumar S, Kumar S, Gautam PK, Singh RK, Verma PK, Singh SP, Acharya A Abstract Natural killer (NK) cells are large granular lymphocytes of the innate immune system and play a pivotal role against virus-infected cells, microbial pathogens, and tumor cells. NK cells secrete several cytokine,s but IFN-γ secreted by NK cells play a vital role in the activation of the innate and adaptive immune systems. But during any infection or tumor burden, functional activity of NK cells is downregulated significantly by nTreg cells. It is also found that during tumor progression, the number of nTreg cells increases as a result; it effectively suppresses the antitumor activity of NK cells. Therefore, in the present investigation, we intend to examine the mechanism of downregulation of antitumor immune response mediated by NK cells. We observed increased NK cell population at an early stage of Dalton's lymphoma (DL) growth, while at late stage, NK cell numbers were decreased. The NK cell functional activity was govern by high level of IFN-γ measurement during tumor progression. The FoxP3(+) CD25(+) CD4(+) T regulatory cell population was found to be continuously increased with high-level expression of FoxP3 during DL growth. The rapid increase in the number of Treg cells during DL p...

Conclusion The present study shows that A. xylosoxidans infection may not be associated with pulmonary B-cell lymphoma in a Japanese case series. Large-scale international studies are needed to clarify the role of A. xylosoxidans in pulmonary lymphoma. PMID: 29151525 [PubMed - as supplied by publisher]

Authors: Hayashi N, Fujita A, Saikai T, Takabatake H, Sotoshiro M, Sekine K, Kawana A Abstract Anaplastic lymphoma kinase (ALK) rearrangement is most commonly observed in lung adenocarcinoma in a subset of lung cancer. Large-cell neuroendocrine carcinoma (LCNEC) harboring an ALK rearrangement is very rare. Based on the findings from a transbronchial lung biopsy, a 75-year-old non-smoking woman was diagnosed with LCNEC with multiple liver and bone metastases. After seven cycles of cytotoxic chemotherapy, her genotype testing demonstrated ALK rearrangement. Subsequently, she was administered alectinib and exhibited a...

Authors: Tanaka Y, Taima K, Tanaka H, Itoga M, Ishioka Y, Shiratori T, Tsuchiya J, Sakamoto H, Takanashi S, Tasaka S Abstract Sarcoidosis is an inflammatory granulomatous disease that is systemic, but bone involvement is uncommon. A 68-year-old man was referred to our hospital complaining of right shoulder pain with numbness. Computed tomography revealed systemic lymphadenopathy and multiple bone lesions. Because malignant lymphoma with a mass lesion protruding into the vertebral canal was considered, he underwent urgent radiotherapy. Thereafter, a needle biopsy of the left parasternal node was performed and showed...
