Ferroptosis, a new form of cell death: mechanisms, biology and role in gynecological malignant tumor.

Ferroptosis, a term coined by Dixon et al. in 2012, refers to an iron-dependent form of regulated cell death driven by an overload of lipid peroxides on cellular membranes. It is morphologically and mechanistically distinct from apoptosis and other types of regulated cell death.

Clinical significance of regulatory T cells and T lymphocyte subsets in peripheral blood in neoadjuvant chemotherapy for breast cancer.

The impact of the immune response on the therapeutical efficacy of neoadjuvant chemotherapy for breast cancer remains largely unknown. To characterize the role of regulatory T cells (CD4CD25CD127Treg), T lymphocyte subsets (CD3, CD4, CD4/CD8) and NK cells in neoadjuvant chemotherapy, we investigated the correlation patterns of these immune cell subsets with the progression of breast cancer. A total of 120 breast cancer patients receiving neoadjuvant chemotherapy in Nanjing Maternal and Child Health Hospital from May 2019 to November 2021 were retrospectively collected as the breast cancer group, and 46 healthy women were selected as the control group.
