Conventional immunoassays, however, often lack specificity and require confirmatory testing with fresh human platelets. To address this limitation, we optimized our previously developed cell-based enzyme-linked immunosorbent assay (ELISA) for improved HIT detection under various experimental conditions. Platelet factor 4 was immobilized on breast cancer cells (MDA-MB-231) to capture monoclonal HIT-like (KKO) and non-HIT (RTO) antibodies, which served as models to evaluate assay performance under different pH levels, ionic strengths (NaCl), and fixation methods (ethanol, paraformaldehyde, glutaraldehyde). To identify the most suitable substrate, additional cancer cell lines (HCT-116, MCF-7, HepG2) were tested under live and fixed conditions, with selected conditions validated using human HIT sera. Optimal detection tested with monoclonal antibodies was achieved using 50 mM NaCl and 4% paraformaldehyde fixation. Notably, live MDA-MB-231 and HCT-116 cells demonstrated superior sensitivity and specificity compared to fixed cells. Furthermore, these cell lines enable the efficient detection of HIT antibodies using flow cytometry, a robust and platelet-free diagnostic method.

The stability and role of FBXO31 may be regulated by specific residual modification. In this study, five FBXO31 phosphorylation sites are identified in HEK293T cells using biochemical and biological techniques.

The regulatory roles of Thr-37 and Ser-523 in FBXO31 stability are associated with variations in phosphorylation levels and degradation pathways.

In contrast, hUC-MSCs display reduced viability and no morphological alterations. Conditioned media from cancer-exposed hUC-MSCs induce apoptosis in A549 cells, whereas hBM-MSCs support A549 growth.

However, lingering questions about the off-target effects of IR stimulation on non-neuronal cells remain sparsely explored. It is shown that rat astroglial cultures are independently sensitive to single pulses of infrared light, evoking calcium signaling and osmoregulatory phenomena in vitro. Recent studies highlight that astrocytes respond differently to electromagnetic and laser stimulation, recruiting different pathways. The impact of three different IR stimulation time courses on astrocyte calcium and water transport dynamics is explored with widefield fluorescence microscopy and pharmacology to fill this gap. Results show that different stimulation methods can evoke astrocyte calcium responses, resulting from distinct biomolecular signaling processes. Notably, swelling and shrinkage are also differently evoked by short-term and long-term stimulation pulses. It is shown that specific IR stimulation can drive selective water and calcium dynamics in astrocytes. The work uniquely reports label-free optical modulation techniques to drive astroglial homeostatic machinery, a crucial process in healthy brain function that lacks tools for spatially precise modulation.
