Abstract

Methamphetamine (Meth) is a widely abused stimulant and its users are at increased risk for multiple infectious diseases. To determine the impact of meth on the immune system, we utilized a murine model that simulates the process of meth consumption in a typical addict. Our phenotypic analysis of leukocytes from this dose escalation model revealed that meth affected key immune subsets. Meth administration led to a decrease in abundance of natural killer (NK) cells and the remaining NK cells possessed a phenotype suggesting reduced responsiveness. Dendritic cells (DCs) and Gr-1(high) monocytes/macrophages were also decreased in abundance while Gr-1(low) monocytes/macrophages appear to show signs of perturbation. CD4 and CD8 T cell subsets were affected by methamphetamine, both showing a reduction in antigen-experienced subsets. CD4 T cells also exhibited signs of activation, with increased expression of CD150 on CD226-expressing cells and an expansion of KLRG1(+), FoxP3(-) cells. These results exhibit that meth has the ability to disrupt immune homeostasis and impact key subsets of leukocytes which may leave users more vulnerable to pathogens.

  • Regular methamphetamine use is associated with various harms and symptoms including psychosis, mood swings, insomnia, skin lesions, depression, malnutrition, respiratory illness, gum disease, severe tooth decay, risky behaviours, and endocarditis.

    “Regular methamphetamine use is associated with various harms and symptoms including psychosis, mood swings, insomnia, skin lesions, depression, malnutrition, respiratory illness, gum disease and severe tooth decay, risky behaviours (e.g., criminal behaviours, injection of other illicit substances, sexual practices that increase risk of sexually transmitted infections), and endocarditis [1, 7–18].”

    From Psychosocial and pharmacologic interventions for problematic methamphetamine use: Findings from a scoping review of the literature (2023) · cites this paper as [7]

    The Introduction (page unavailable) reports sleeplessness, reduced appetite, and increased infection risk linked to risky sexual practices and intravenous drug use. It does not establish several other listed harms, including psychosis, depression, dental disease, respiratory illness, and endocarditis; reduced appetite alone does not establish malnutrition.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
