Nicotine enhances the stemness and tumorigenicity in intestinal stem cells via Hippo-YAP/TAZ and Notch signal pathway.

Cigarette smoking is a well-known risk factor inducing the development and progression of various diseases. Nicotine (NIC) is the major constituent of cigarette smoke. However, knowledge of the mechanism underlying the NIC-regulated stem cell functions is limited.

Mechanical signaling through membrane tension induces somal translocation during neuronal migration.

Neurons migrate in a saltatory manner by repeating two distinct steps: extension of the leading process and translocation of the cell body. The former step is critical for determining the migratory route in response to extracellular guidance cues. In the latter step, neurons must generate robust forces that translocate the bulky soma against mechanical barriers of the surrounding three-dimensional environment.

Pathological Complete Response to a Single Dose of Pembrolizumab-Based Chemoimmunotherapy for Squamous Cell Carcinoma of the Lung: A Case Report.

We herein describe a patient with non-small-cell lung cancer who achieved pCR with a single dose of pembrolizumab-based chemoimmunotherapy followed by surgery. A 61-year-old man was referred to our hospital with wheezing and an abnormal chest shadow. Squamous cell carcinoma of the left lower lobe, cT2aN1M0 stage IIB, was diagnosed and pembrolizumab-based chemoimmunotherapy was initiated at the patient's request.

Stress-experienced monocytes/macrophages lose anti-inflammatory function via β-adrenergic receptor in skin allergic inflammation.

Background: Psychological stress can exacerbate the development of allergies; however, the underlying mechanisms remain poorly understood. IgE-mediated cutaneous allergic inflammation (IgE-CAI) is a basophil-dependent skin allergy with eosinophil infiltration at inflammatory sites. Its resolution involves anti-inflammatory programmed death ligand 2 (PD-L2)-positive macrophages.

Structural diversity and function of the granulocyte colony-stimulating factor in medaka fish.

Diversity in the granulocyte repertoire, including neutrophils, basophils, and eosinophils, has been reported in vertebrate species. Medaka fish (Oryzias latipes) have only neutrophils; however, the storage pool of granulopoiesis tissues and the molecular mechanism of granulopoiesis in medaka fish have not been explored. Granulocyte colony-stimulating factor (G-CSF) is a cytokine responsible for neutrophil differentiation, survival, and proliferation.
