PLGA-PEG-PLGA hydrogels induce cytotoxicity in conventional in vitro assays (2024)
Journal Article
Stewart, C. L., Hook, A. L., Zelzer, M., Marlow, M., & Piccinini, A. M. (2024). PLGA-PEG-PLGA hydrogels induce cytotoxicity in conventional in vitro assays. Cell Biochemistry and Function, 42(5), Article e4097. https://doi.org/10.1002/cbf.4097

We identified that PLGA-PEG-PLGA hydrogels, which have been used in human clinical trials and possess a demonstrable safety profile, induced significant cytotoxicity in conventional in vitro assays. This major contradiction may lead to inconsistent a... Read More about PLGA-PEG-PLGA hydrogels induce cytotoxicity in conventional in vitro assays.

Cellular and microenvironmental cues that promote macrophage fusion and foreign body response (2024)
Journal Article
Stewart, C. L., Marlow, M., Zelzer, M., Hook, A. L., & Piccinini, A. M. (in press). Cellular and microenvironmental cues that promote macrophage fusion and foreign body response. Frontiers in Immunology, 15, https://doi.org/10.3389/fimmu.2024.1411872

During the foreign body response (FBR), macrophages fuse to form foreign body giant cells (FBGCs). Modulation of FBGC formation can prevent biomaterial degradation and loss of therapeutic efficacy. However, the microenvironmental cues that dictate FB... Read More about Cellular and microenvironmental cues that promote macrophage fusion and foreign body response.

A virological view of tenascin-C in infection (2022)
Journal Article
Zuliani-Alvarez, L., & Piccinini, A. M. (2023). A virological view of tenascin-C in infection. American Journal of Physiology - Cell Physiology, 324(1), C1-C9. https://doi.org/10.1152/ajpcell.00333.2022

Tenascin-C is a large extracellular matrix glycoprotein with complex, not yet fully unveiled roles. Its context- and structure-dependent modus operandi renders tenascin-C a puzzling protein. Since its discovery ∼40 years ago, research into tenascin-C... Read More about A virological view of tenascin-C in infection.

miR-155-3p: processing by-product or rising star in immunity and cancer? (2022)
Journal Article
Dawson, O., & Piccinini, A. M. (2022). miR-155-3p: processing by-product or rising star in immunity and cancer?. Open Biology, 12(5), 843-854. https://doi.org/10.1098/rsob.220070

MicroRNAs (miRNAs) are key players in gene regulation that target specific mRNAs for degradation or translational repression. Each miRNA is synthesized as a miRNA duplex comprising two strands (5p and 3p). However, only one of the two strands becomes...

Therapeutic Effects of Hypoxic and Pro-Inflammatory Priming of Mesenchymal Stem Cell-Derived Extracellular Vesicles in Inflammatory Arthritis (2021)
Journal Article
Kay, A. G., Treadwell, K., Roach, P., Morgan, R., Lodge, R., Hyland, M., Piccinini, A. M., Forsyth, N. R., & Kehoe, O. (2022). Therapeutic Effects of Hypoxic and Pro-Inflammatory Priming of Mesenchymal Stem Cell-Derived Extracellular Vesicles in Inflammatory Arthritis. International Journal of Molecular Sciences, 23(1), Article 126. https://doi.org/10.3390/ijms23010126

Mesenchymal stem cells (MSCs) immunomodulate inflammatory responses through paracrine signalling, including via secretion of extracellular vesicles (EVs) in the cell secretome. We evaluated the therapeutic potential of MSCs-derived small EVs in an an...

A complex interplay between the extracellular matrix and the innate immune response to microbial pathogens (2018)
Journal Article
Tomlin, H., & Piccinini, A. M. (2018). A complex interplay between the extracellular matrix and the innate immune response to microbial pathogens. Immunology, 155(2), 186-201. https://doi.org/10.1111/imm.12972

The role of the host extracellular matrix (ECM) in infection tends to be neglected. However, the complex interactions between invading pathogens, host tissues and immune cells occur in the context of the ECM. On the pathogen side, a variety of surfac...

Mesenchymal stem cell-conditioned medium reduces disease severity and immune responses in inflammatory arthritis (2017)
Journal Article
Kay, A. G., Long, G., Tyler, G., Stefan, A., Broadfoot, S. J., Piccinini, A. M., …Kehoe, O. (2017). Mesenchymal stem cell-conditioned medium reduces disease severity and immune responses in inflammatory arthritis. Scientific Reports, 7, Article 18019. https://doi.org/10.1038/s41598-017-18144-w

We evaluated the therapeutic potential of mesenchymal stem cell-conditioned medium (CM-MSC) as an alternative to cell therapy in an antigen-induced model of arthritis (AIA). Disease severity and cartilage loss were evaluated by histopathological anal...

Nature Communications, 8(1), Article 1595. https://doi.org/10.1038/s41467-017-01718-7

© 2017 The Author(s). Pattern recognition underpins innate immunity; the accurate identification of danger, including infection, injury, or tumor, is key to an appropriately targeted immune response. Pathogen detection is increasingly well defined me... Read More about Mapping tenascin-C interaction with toll-like receptor 4 reveals a new subset of endogenous inflammatory triggers.

An immune response can be activated by pathogenic stimuli, as well as endogenous danger signals, triggering the activation of pattern recognition receptors and initiating signalling cascades that lead to inflammation. This method uses THP1-Blue™ cell... Read More about Screening for novel endogenous inflammatory stimuli using the secreted embryonic alkaline phosphatase NF-κB reporter assay.
