Although protein subunit vaccines generally have acceptable safety profiles with precise antigenic content, limited immunogenicity can lead to unsatisfactory humoral and cellular immunity and the need for vaccine adjuvants and delivery system. Herein, we assess a vaccine adjuvant system comprising Quillaja Saponaria-21(QS-21) and cobalt porphyrin polymeric micelles that enabling the display of His-tagged antigen on its surface. The nanoscale micelles promote antigen uptake and dendritic cell activation to induce robust cytotoxic T lymphocyte response and germinal center formation. Using the recombinant protein antigens from influenza A and rabies virus, the micelle adjuvant system elicited robust antiviral responses and protected mice from lethal challenge. In addition, this system could be combined with other antigens to induce high titers of neutralizing antibodies in models of three highly pathogenic viral pathogens: Ebola virus, Marburg virus, and Nipah virus. Collectively, our results demonstrate this polymeric micelle adjuvant system can be used as a potent nanoplatform for developing antiviral vaccine countermeasures that promote humoral and cellular immunity.

The autoimmune/inflammatory syndrome induced by adjuvants (ASIA) is a rare condition caused by an immune response associated with over-reactivity of the immune system, triggered by adjuvants. The most common adjuvants are aluminium salts but can also be bioimplants or infectious agents. It may lead to the development of various autoimmunologic diseases.

Department of Obstetrics and Gynecology, Taipei Veterans General Hospital, Taipei, Taiwan; School of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan; Institute of Clinical Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan. Electronic address:

Objective: Approximately 10-15 % of endometrial cancer patients with tumors confined to the uterus (FIGO 2009 stage I) demonstrate recurrence and the oncologic outcomes are highly related to recurrence patterns. This study aimed to verify whether the FIGO 2023 staging system could discriminate outcomes.

Materials And Methods: Between January 2010 and March 2019, 536 FIGO 2009 stage I patients were eligible for this retrospective cohort study.

Breast cancer remains the second most prevalent cancer among women in the United States. Despite advancements in surgical, radiological, and chemotherapeutic techniques, multidrug resistance continues to pose significant challenges in effective treatment. Combination chemotherapy has emerged as a promising approach to address these limitations, allowing multiple drugs to target malignancies via distinct mechanisms of action.

Background: Metastatic retinoblastoma remains a significant challenge in pediatric oncology, with stark disparities in survival outcomes between high-income countries (HICs) and low-income countries (LICs). Delayed diagnosis and treatment, driven by socioeconomic factors and limitations in healthcare systems, contribute to poorer outcomes in LICs. Histopathological characteristics, including high-risk pathology factors (HRPFs) and the extent of ocular tumor invasion, are critical for predicting metastatic risk and guiding treatment strategies.

The etiological agent for the coronavirus disease 2019 (COVID-19), the SARS-CoV-2, caused a global pandemic. Although mRNA, viral-vectored, DNA, and recombinant protein vaccine candidates were effective against the SARS-CoV-2 Wuhan strain, the emergence of SARS-CoV-2 variants of concern (VOCs) reduced the protective efficacies of these vaccines. This necessitates the need for effective and accelerated vaccine development against mutated VOCs.
