To observe the changes of autophagy-related protein levels in peripheral blood lymphocytes before and after sirolimus treatment in children with systemic lupus erythematosus (SLE). Children with SLE were randomly divided into two groups, 28 in the traditional treatment group and 28 in the sirolimus group. Fifteen healthy children who were in the same period were collected as the normal control group. Clinical laboratory indexes, the percentage of routine lymphocytes, complement C3, complement C4, serum Anti-dsDNA and SLEDAI were detected. At 3 and 6 months after treatment, compared with the traditional treatment group, the percentage of routine lymphocytes in the sirolimus group increased ( = 0.03), SLEDAI score and positive rate of Anti-dsDNA decreased ( = 0.01). Compared with normal children, the expression of microtubule-associated protein 1 light chain 3 (LC3) protein in peripheral blood lymphocytes was significantly higher ( = 0.006); peripheral blood expression of P62/SQSTM1 (sequestosome 1) protein in lymphocytes decreased ( = 0.02). Sirolimus can play a role in the treatment of systemic lupus erythematosus by regulating the level of autophagy.

Novel research model for in vitro immunotherapy: co-culturing tumor organoids with peripheral blood mononuclear cells.

Tumor organoids have emerged as powerful tools for in vitro cancer research due to their ability to retain the structural and genetic characteristics of tumors. Nevertheless, the absence of a complete tumor microenvironment (TME) limits the broader application of organoid models in immunological studies. Given the critical role of immune cells in tumor initiation and progression, the co-culture model of organoids and peripheral blood mononuclear cells (PBMCs) may provide an effective platform for simulating the interactions between immune and tumor cells in vitro.

Background: Coronary artery disease (CAD) has become a dominant economic and health burden worldwide, and the role of autophagy in CAD requires further clarification. In this study, we comprehensively revealed the association between autophagy flux and CAD from multiple hierarchies. We explored autophagy-associated long noncoding RNA (lncRNA) and the mechanisms underlying oxidative stress-induced human coronary artery endothelial cells (HCAECs) injury.

Methods: The retrospective study cohort comprised 40 patients diagnosed with first-episode SCZ (SCZ group) and 40 healthy individuals (control group). Quantitative analyses were conducted on five complement factors, namely complement component 1 (C1), C2, C3, C4, and the 50% hemolytic complement (CH50).
Sequential STING and CD40 agonism drives massive expansion of tumor-specific T cells in liposomal peptide vaccines.

The clinical use of cancer vaccines is hampered by the low magnitude of induced T-cell responses and the need for repetitive antigen stimulation. Here, we demonstrate that liposomal formulations with incorporated STING agonists are optimally suited to deliver peptide antigens to dendritic cells in vivo and to activate dendritic cells in secondary lymphoid organs. One week after liposomal priming, systemic administration of peptides and a costimulatory agonistic CD40 antibody enables ultrarapid expansion of T cells, resulting in massive expansion of tumor-specific T cells in the peripheral blood two weeks after priming.

Diabetes is an incurable, chronic disease that can lead to many complications, including angiopathy, peripheral neuropathy, and erectile dysfunction (ED). The angiopoietin-Tie2 signaling pathway plays a critical role in blood vessel development, formation, remodeling, and peripheral nerve regeneration. Therefore, strategies for activating the Tie2 signaling pathway have been developed as potential therapies for neurovascular diseases.
