Neutrophilic granulocytes are able to release their own DNA as neutrophil extracellular traps (NETs) capture and eliminate pathogens. expulsion (NETosis) has also been documented for other cells organisms, thus highlighting the evolutionary conservation of this process. Moreover, dysregulated NETosis implicated in many diseases, including cancer inflammatory disorders. During NETosis, neutrophils undergo dynamic dramatic alterations cellular well sub-cellular morphology whose biophysical...

Oligonucleotides are promising drug candidates due to the exceptionally high specificity they exhibit toward their target DNA and RNA sequences. However, poor pharmacokinetic pharmacodynamic properties, in conjunction with problems associated internalization by cells, necessitates delivery through specialized carrier systems for efficient therapy. Here, we investigate effects of morphology on cellular mechanisms oligonucleotides using self-assembled fibrous or spherical peptide...

Immunogenic cell death (ICD) arises when cells are under stress, and their membranes damaged. They release damage-associated molecular patterns (DAMPs) that stimulate drive the type magnitude of immune response. In presence an antigen, DAMPs ride longevity efficacy antigen-specific immunity. Yet, no tool can induce controlled ICD with predictable results. A peptide-based tool, [II], is designed aggregates in causes membrane damage, generates on various types, hence act as adjuvant.

Optical coherence tomography (OCT) is an ideal imaging technique for noninvasive and longitudinal monitoring of multicellular tumor spheroids (MCTS). However, the internal structure features within MCTS from OCT images are still not fully utilized. In this study, we developed cross-statistical, cross-screening, composite-hyperparameter feature processing methods in conjunction with 12 machine learning models to assess changes structure. Our results indicated that effective combined...
