Yunnan Key Laboratory of Vaccine Research and Development for Severe Infectious Diseases, Institute of Medical Biology, Chinese Academy of Medicine Sciences & Peking Union Medical College, Kunming 650118, China.

Due to the complex pathogenic and immune escape mechanisms of herpes simplex virus type 1 (HSV-1), especially the failure of induced immune responses to block the initial cell-to-cell transmission of the virus from skin cells to neurons, the body struggles to establish effective prevention and control methods, resulting in the failure of currently developed vaccines. Previous studies have highlighted the crucial roles of surface glycoproteins and nucleocapsid proteins in activating the body's immune defense system against HSV-1 infection. In this study, recombinant adenoviruses were used as vectors to generate adenoviruses carrying the nucleocapsid protein genes UL18 and UL25, as well as the surface glycoprotein gene gB.

Background: Dengue virus (DENV) is the most widespread mosquito-borne virus, which can cause dengue fever with mild symptoms, or progress to fatal dengue hemorrhagic fever and dengue shock syndrome. As the main target cells of DENV, macrophages are responsible for the innate immune response against the virus.

Methods: In this study, we investigated the role of pyroptosis in the pathogenic mechanism of dengue fever by examining the level of pyroptosis in DENV-1-infected macrophages and further screened differentially expressed microRNAs by high-throughput sequencing to predict microRNAs that could affect the pyroptosis of the macrophage.

Chikungunya virus (CHIKV) is a mosquito-borne alphavirus that is primarily known for causing severe joint and muscle symptoms, but its pathological effects have extended beyond these tissues. In this study, we conducted a comprehensive proteomic analysis across various organs in rodent and nonhuman primate models to investigate CHIKV's impact on organs beyond joints and muscles and to identify key host factors involved in its pathogenesis. Our findings reveal significant species-specific similarities and differences in immune responses and metabolic regulation, with proteins like Interferon-Stimulated Gene 15 (ISG15) and Retinoic Acid-Inducible Gene I (RIG-I) playing crucial roles in the anti-CHIKV defense.
