Herpes simplex virus type 1 impairs mucosal-associated invariant T cells.
Article in mBio, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Herpes simplex virus type 1 (HSV-1) is a highly successful pathogen that infects mucosal sites and adopts an arsenal of strategies to manipulate host immunity. Mucosal-associated invariant T (MAIT) cells are abundant innate-like T lymphocytes that recognize bacterial and fungal-derived vitamin B-related metabolites presented by major histocompatibility complex class I-related protein 1 (MR1). MAIT cells can also be activated in an MR1-independent manner via cytokine stimulation, predominantly by IL-12 and IL-18. MAIT cell alterations have been identified as being associated with a number of viral infections, but direct interactions between viruses and MAIT cells are poorly understood. It is unknown whether HSV-1 can infect MAIT cells and modulate their functions. Here, we show that HSV-1 can infect primary human MAIT cells, including CD4 IMPORTANCE: Mucosal-associated invariant T cells (MAIT cells) are "unconventional" immune cells that are becoming increasingly appreciated to play important roles in a variety of viral infections. Herpes simplex virus (HSV) causes significant human disease and is a master manipulator of multiple immune functions, but how this virus may control MAIT cells is poorly understood. We discovered that HSV can infect human MAIT cells and impair their functional capacity and also show that MAIT cells exposed to HSV, but which do not show evidence of infection, are similarly impaired. This study therefore identifies an additional immunomodulatory function of HSV.
