Background: Alzheimer's disease (AD) is a debilitating neurodegenerative disorder that is difficult to predict and is typically diagnosed only after symptoms manifest. Recently, CD4 T cell-derived double-negative T (DNT) cells have shown strong immuno-regulatory properties in both in vitro and in vivo neuronal inflammation studies. However, the effectiveness of DNT cells in treating on AD are not yet fully understood.

Background: Ewing's sarcoma (EwS), a common pediatric bone cancer, is associated with poor survival due to a lack of therapeutic targets for immunotherapy or targeted therapy. Therefore, more effective treatment options are urgently needed.
Methods: Since novel immunotherapies may address this need, we performed an integrative analysis involving single-cell RNA sequencing, cell function experiments, and humanized models to dissect the immunoregulatory interactions in EwS and identify strategies for optimizing immunotherapeutic efficacy.
Potential regulation of artesunate on bone metabolism through suppressing inflammatory infiltration in type 2 diabetes mellitus.

Objective: Osteoimmunology is an emerging field that explores the interplay between bone and the immune system. The immune system plays a critical role in the pathogenesis of diabetes and significantly affects bone homeostasis. Artesunate, a first-line treatment for malaria, is known for its low toxicity and multifunctional properties.

FoxP3 T-regulatory (Treg) lymphocytes and cytokine production by cells from the stromal vascular fraction (SVF) of epicardial (EAT) and thymus (TAT) adipose tissue of 42 patients with chronic coronary heart disease (CHD) were studied. In the SVF of TAT in patients with Gensini Score (GS)≥74 (the most severe atherosclerosis), the production of IL-1β, TNF, IL-4, and IFNγ was higher, while FoxP3 translocation into the nucleus was lower than in patients with GS<74. The GS index directly correlated with the production of IL-4, IL-1β, and TNF by cells of the SVF of TAT, and inversely - with the production of TNF, IL-17, and IL-10 by cells of the SVF of EAT.

Article Synopsis
- Tolerogenic vaccines aim to create immune tolerance specifically for disease-related antigens, offering a safer alternative to broad immunosuppression, which can lead to infections and weakened anti-tumor responses.
- They work by promoting certain immune cells that help regulate and suppress harmful immune responses, thus targeting conditions like autoimmunity and transplant rejection.
- The design of these vaccines varies, often involving a relevant antigen paired with a tolerogenic adjuvant that enhances their effectiveness by creating a more favorable immune response through multiple mechanisms.
