Should We Advance Our Understanding of Immunoglobulin E in Viral Immunity?

Immunology, Volume 176, Issue 3, Page 312-321, November 2025.
Immunoglobulin E has been extensively studied in allergies and parasitic diseases. Antigen‐specific IgE has been identified as part of the humoral response to viruses. This revision speculates on possible functionalities for IgE, such as neutralisation, cytotoxicity and immunopathology of viral diseases, and provide insights about gaps to fill in ...

Human T Cell Responses to Flavivirus Vaccines

European Journal of Immunology, Volume 55, Issue 8, August 2025.
This review summarises current knowledge of T cell responses induced by flavivirus vaccines being licensed or under development. Existing vaccines against flaviviruses have been developed and analysed primarily in the context of antibody responses, while the role of T cells in contributing to immunity against flaviviruses is less studied.
