The impact of growth hormone (GH) on immunosenescence: exploring the role of B and T cells.
Article in Pituitary, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeImmunosenescence is a gradual decline in immune function, leading to increased susceptibility to infections and autoimmune conditions. Growth hormone (GH) has been shown to have an effect on both immune function and aging. In fact, the absence of GH-induced intracellular signaling can slow the aging process, as demonstrated by the longest-lived laboratory mouse (GH receptor gene disrupted or GHR-/- mice). Because GH receptors (GHR) are expressed in B and T cells, and these cells undergo age-related changes that impact immune function, we hypothesized that decreased GH action protects from immunosenescence. To validate this hypothesis, this study aimed to characterize differences in B cell and T cell populations within the lymphoid organs of aged female GHR-/- mice (24 months of age) compared to wild-type controls.
methodsB and T cell populations in mouse blood, spleen, thymus, and bone marrow (BM) were analyzed by multicolor flow cytometry.
resultsThe current study showed significantly higher levels of anti-inflammatory follicular (FO) B cells in spleens and BM and lower levels of pro-inflammatory aging-associated B cells (ABC) in the spleens, BM, and blood of aged GHR-/- mice compared to WT mice. In addition, T cell populations in aged GHR-/- mice showed higher levels of naïve T cells and lower levels of memory T cells in the thymus, BM, spleen, and blood.
conclusionFemale GHR-/- mice are protected from age-related shifts in lymphocyte populations, suggesting that the absence of GH action mitigates immunosenescence. These results offer novel insights into mechanisms and therapeutic strategies to preserve immune balance and combat age-related immune dysfunction.
