Tubulin-Based Microtentacles Aid in Heterotypic Clustering of Neutrophil-Differentiated HL-60 Cells and Breast Tumor Cells.

Circulating tumor cells (CTCs) travel through the vasculature to seed secondary sites and serve as direct precursors of metastatic outgrowth for many solid tumors. Heterotypic cell clusters form between CTCs and white blood cells (WBCs) and recent studies report that a majority of these WBCs are neutrophils in patient and mouse models. The lab discovered that CTCs produce tubulin-based protrusions, microtentacles (McTNs), which promote reattachment, retention in distant sites during metastasis and formation of tumor cell clusters.

Microgravity Effects on Glioma Cells: A Comprehensive Review.

High-grade gliomas (HGGs) represent a formidable challenge in neuro-oncology due to their aggressive nature and resistance to current therapeutic interventions, which include surgery, radiation, chemotherapy, and emerging immunotherapies. Despite these efforts, the prognosis for patients remains poor, emphasizing the urgent need for novel treatment strategies. One promising avenue of exploration is microgravity, a condition experienced during spaceflight and simulated in laboratories on Earth, which induces significant physiological changes in cells and tissues.

IFNλ signaling in neutrophils enhances the pathogenesis of Bordetella pertussis infection.

Interferon lambda (IFN-λ) plays diverse roles in bacterial infections. Previously we showed that IFN-λ is induced in the lungs of B. pertussis-infected adult mice and exacerbates inflammation.
