Cardiac dose distribution differs with modern techniques like intensity-modulated radiotherapy (IMRT), potentially affecting this relationship. This study evaluates long-term cardiac toxicity in breast cancer patients treated with tomotherapy to reassess 3D-derived dose constraints. Breast cancer patients treated with tomotherapy at Institut Curie from August 2010 to December 2015 were included. Patients had undergone breast-conserving surgery or mastectomy, with some receiving chemotherapy or trastuzumab. Tomotherapy was used for anatomically challenging cases. The primary endpoint was cardiac toxicity correlated with MHD; secondary endpoints were overall and disease-specific survival. Statistical analyses included logistic regression and Cox models. Among 179 patients, the median MHD was 7.04 Gy, with 95.6% having an MHD above 5 Gy. Sixty-six patients had cardiovascular risk factors, and 28.5% were obese. Over a median follow-up of 9.1 years, eight patients (4.5%) experienced cardiovascular events-all with pre-existing risks or obesity. No significant correlation was found between MHD and major coronary events (p = 0.607) or heart failure (p = 0.800). Cardiac mortality was absent, and 10-year overall and disease-specific survival were 88.0% and 94.3%, respectively. Cardiac events in patients treated with tomotherapy were rare and driven by pre-existing risk factors. The linear MHD-toxicity relationship observed in 3D radiotherapy may not apply to IMRT, potentially leading to overestimated risks.

The transient receptor potential melastatin 2 (TRPM2) is a calcium-permeable nonselective channel involved in the pathological mechanism of several inflammatory and neurodegenerative diseases. However, the role of TRPM2 in inflammation and microglial activation in the context of PD remains unclear. Here, we combined both in vivo and in vitro PD models to investigate that question. Male and female TRPM2 partial and complete knockout mice were submitted to the 6-hydroxidopamine mouse model of PD. We assessed microglia and lysosome-associated protein (CD68) density levels, microglial morphology and cluster classification, CD68 area in individual microglial cells, and the protein levels of six different cytokines in the substantia nigra pars compacta and the striatum. Our results indicate that TRPM2 deletion reduced microglial density, rescued its morphology, decreased CD68 staining area within microglia, and lowered pro-inflammatory cytokines levels in both male and female mice. To better understand TRPM2 involvement in PD pathology, we selectively knocked-down TRPM2 in neurons, microglia, or both cells in a human neuron-microglia co-culture PD model. An improvement in cell viability and a decrease in cell death were observed across the different experimental approaches. Lastly, TRPM2 deletion revealed reduced microglial phagocytosis and decreased expression of inflammation-related molecules. For the first time, we demonstrated that TRPM2 is a critical mediator of microglial function in the context of PD.

Employing animal models, we demonstrate that chronic stress could dysregulate HSP60 in the brain of mice concurrent with inducing depressive-like symptoms in mice. Furthermore, astrocyte-specific HSP60 depletion (HSP60 cKO) male mice exhibited depressive-like behaviors, alongside significant disruption in astrocyte morphology and impaired autophagic processes within the cortex.
