The involvement of arbuscular mycorrhizal fungi in modulating polyamine metabolism and low-temperature tolerance enhancement in white clover

Frontiers in Plant Science
Sustained low temperatures can prevent white clover (Trifolium repens L.) from overwintering and regreening, making it difficult to revive the plants in the spring.

Perturbation of Spermine Homoeostasis Uncouples Hypersensitive Cell Death From Systemic Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

Prevalence of autoantibodies to the 65- and 67-kD isoforms of glutamate decarboxylase in insulin-dependent diabetes mellitus [PDF]

, 1993
We investigated the presence of autoantibodies to baculovirus-expressed human recombinant 65- and 67-kD isoforms of glutamate decarboxylase (GAD65 and GAD67) in insulin-dependent diabetes mellitus (IDDM).

Putrescine Plays a Positive Role in Salt-Tolerance Mechanisms by Reducing Oxidative Damage in Roots of Vegetable Soybean

Journal of Integrative Agriculture, 2014
Polyamines play important roles in plant tolerance to environmental stress. With the aim of investigating the possible involvement of putrescine (Put) in salt-tolerance mechanisms in vegetable soybean roots, exogenous Put (10 mmol L−1) and its ...

Müller Glia Subtypes Define Neuro‐Glial Associations and Spatial Morphogen Axes in the Zebrafish Retina

Glia, Volume 74, Issue 11, November 2026.
Zebrafish Müller glia are heterogeneous in the early larval retina. Zebrafish Müller glia subtypes define a spatial axis of retinoic acid metabolism. Neuron‐associated glial programs identified in Zebrafish Müller glia are evolutionarily conserved in mammals. ABSTRACT Müller glia are instrumental macroglia of the vertebrate retina, once thought to be a

The role of arginine and arginine-metabolizing enzymes during Giardia - host cell interactions in vitro [PDF]

, 2013
Background: Arginine is a conditionally essential amino acid important in growing individuals and under nonhomeostatic conditions/disease. Many pathogens interfere with arginine-utilization in host cells, especially nitric oxide (NO) production, by ...

Essential Oral Single Nutritional Therapy Products for Inherited Metabolic Diseases: Evidence and Consensus Assessment Using a Modified Delphi Method

Journal of Inherited Metabolic Disease, Volume 49, Issue 6, November 2026.
ABSTRACT Nutritional therapy is critical in managing inherited metabolic diseases (IMDs), and includes specialized diets and single nutritional therapy products (sNTPs) such as vitamins, cofactors, and amino acids. Many sNTPs function as medicines, but are regulated as food (e.g., food supplements), which can limit access, reimbursement, and consistent

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis

Immunology, Volume 179, Issue 3, Page 418-433, November 2026.
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...
