Photodynamic therapy (PDT) has emerged as an innovative approach in cancer treatment, effectively inducing tumor cell death through light-triggered reactive oxygen species (ROS) generation. Additionally, PDT can also trigger antitumor immune responses, thereby reducing the risk of postoperative tumor recurrence. However, the development of highly efficient photosensitizers aimed at activating immune responses for comprehensive tumor eradication remains at an early stage.

Here, we conducted a comprehensive three-year longitudinal study examining T cell and antibody responses in 78 vaccinated individuals without reported symptomatic infections. We observed distinct dynamics in Spike-specific humoral and cellular immune responses across multiple vaccine doses.

Background: Primary heart involvement (pHI) is frequent in systemic sclerosis (SSc), and is associated with a poor prognosis. Therapeutic strategies to treat SSc-pHI are not yet defined.
Objectives: To evaluate the efficacy of immunosuppressive therapy on cardiac magnetic resonance (CMR) features in patients with CMR-proven SSc-pHI.
Nr4a1 and Nr4a3 redundantly control clonal deletion and contribute to an anergy-like transcriptome in auto-reactive thymocytes to impose tolerance in mice.

The Nr4a nuclear hormone receptors are transcriptionally upregulated in response to antigen recognition by the T cell receptor (TCR) in the thymus and are implicated in clonal deletion, but the mechanisms by which they operate are not clear. Moreover, their role in central tolerance is obscured by redundancy among the Nr4a family members and by their reported functions in Treg generation and maintenance. Here we take advantage of competitive bone marrow chimeras and the OT-II/RIPmOVA model to show that Nr4a1 and Nr4a3 are essential for the upregulation of Bcl2l11/BIM and thymic clonal deletion by self-antigen.
