Objective: To investigate the effect of thymosin alpha1 on immunological function and protein metabolism in peritoneal sepsis rats.
Methods: We observed the effect of thymosin alpha1 on T cell subclassification, TNFalpha, IL-6, IL-10, albumin, C-reactive protein (CRP) and mortality in cecal ligation and puncture (CLP) induced septic rats.
Results: Concentration of TNFalpha and IL-6 in CLP induced septic rats increased significantly, and concentration of IL-10 decreased significantly compared to control group. Thymosin alpha1 significantly decreased TNFalpha, IL-6, and significantly raised concentration of plasma IL-10, percent of CD(3), CD(4), and CD(4)/CD(8) in septic group. Thymosin alpha1 reduced degressive degree of albumin. Concentration of CRP increased in both septic groups, but was less prominently in thymosin alpha1 treated group. Thymosin alpha1 reduced cumulate 7-day mortality.
Conclusion: Thymosin alpha1 can improve immunological function, inflammation condition and protein metabolism.

Background: Liver metastasis is highly aggressive and immune tolerant, and lacks effective treatment strategies. This study aimed to develop a neoantigen hydrogel vaccine (NPT-gels) with high clinical feasibility and further investigate its efficacy and antitumor molecular mechanisms in combination with immune checkpoint inhibitors (ICIs) for the treatment of liver metastases.
Methods: The effects of liver metastasis on survival and intratumor T-cell subpopulation infiltration in patients with advanced tumors were investigated using the Surveillance, Epidemiology, and End Results Program (SEER) database and immunofluorescence staining, respectively.

This systematic review was conducted to assess the curative effect of Thymosin alpha 1 in the acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients. Six electronic databases including EMBASE, PubMed, Cochrane Library, China National Knowledge Infrastructure Database, Chinese Biomedical Database, and Wanfang Database were searched for eligible papers focusing on the thymosin alpha 1 treatment in AECOPD patients. The effectiveness outcomes included T cell subset, pulmonary function, arterial blood gases, and the length of hospital stay.

Article Synopsis
- Oncolytic adenoviruses are being studied for their ability to kill cancer cells and modulate the immune response, but their potential immunosuppressive effects need further investigation.
- This study shows that type V adenoviruses can change the behavior of tumor-associated macrophages (TAMs) and increase regulatory T cells (Tregs) in the tumor microenvironment, which can hinder immune responses against tumors.
- Thymosin alpha 1 (Tα1) can reprogram these macrophages to support anti-tumor activity and enhance the effectiveness of the adenovirus in fighting cancer, indicating a promising direction for future cancer therapies.

Background: Glioblastoma (GBM) is the most common primary malignant brain tumor with very poor prognosis due to frequent recurrence and short overall survival (OS) time, which according to different sources, is not longer than 17 months after the diagnosis. Infiltrative growth pattern often leads to tumor propagation into functionally significant brain areas while surgery is cytoreductive and does not necessarily alter the prognosis. Many patients are in the working age, thus finding conservative approaches to the treatment of this type of neoplasms is of utmost importance.

Rationale: Triple-negative breast cancer is characterized by a worse prognosis compared with other breast cancer subtypes, especially in the case of pretreated metastatic triple-negative breast cancer (mTNBC). Because of the limited treatment options and suboptimal response rates, there is a pressing need to explore novel treatment protocols.
Patient Concerns: A 48-year-old female patient diagnosed with mTNBC who had not responded to multiple lines of therapy (including surgery, chemotherapy, and radiotherapy) but demonstrated significant efficacy and abscopal effects after enrolling in our clinical trial.
