Low-Density-Lipoprotein Receptor and 3-Hydroxy-3-Methylglutaryl Coenzyme-A Reductase Gene-Expression in Human Mononuclear Leukocytes Is Regulated Coordinately and Parallels Gene-Expression in Human Liver

open access: yes, 1994
The liver plays a key regulatory role in cholesterol metabolism. Two proteins are central in this role; the LDL receptor and 3-hydroxy-3-methylglutaryl CoA reductase (HMG CoA reductase), the rate-limiting enzyme in cholesterol biosynthesis.

Bovine colostrum and immune function after exercise [PDF]

open access: yes, 2012
Strenuous and/or prolonged exercise causes transient perturbations in immune function. It is well accepted that this is one mechanism contributing to the higher occurrence of infection (e.g.

Intrasplenic Thymus Organogenesis from Injectable Tissue Fragments Restores Functional T‐Cell Immunity

open access: yesAdvanced Science, EarlyView.
Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

Targeting the NR1D1–IGF2BP2–V‐ATPase Axis With Hybrid Nanovesicles Restores Macrophage Rhythms to Reverse Sepsis‐Induced Immunosuppression

open access: yesAdvanced Science, EarlyView.
Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense.

The role of Th1/Th2 disbalanced immune response in the determination of clinical features of autoimmune diabetes mellitus

open access: yesСахарный диабет, 2011
Aim. To elucidate the role of Th1/Th2 polarization of immune response in LADA patients in the realization of the clinical phenotype of the disease. Materials and methods. 70 patients aged 21-61 (mean 41.3?1.0 yr) with DM diagnosed based on WHO criteria

D4F‐Functionalized Ceria Nanozyme‐CasRx Platform Suppresses STING and Reprograms the Renal Immune Niche in Acute Kidney Injury

open access: yesAdvanced Science, EarlyView.
D4F‐functionalized ceria nanozyme–CasRx nanoparticles preferentially target renal macrophages through SR‐B1‐mediated uptake in ischemia–reperfusion injury. Ceria scavenges excessive ROS, while CasRx silences STING signaling, shifting macrophages toward a less inflammatory, pro‐resolving state and increasing the proportion of regulatory T cells.

Androgen binding sites in peripheral human mononuclear leukocytes of healthy males and females.

open access: yes, 1994
Androgen binding sites have been identified in circulating human mononuclear leukocytes of healthy donors of both sexes. Cells were separated from blood samples on a Ficoll gradient and incubated with different concentrations of [3H]testosterone in the ...

Leveraging Microphysiological Systems to Facilitate Neutrophil‐Based Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
Microphysiological systems are emerging as powerful human‐relevant platforms for studying neutrophil biology in cancer. Current applications of spheroids, organoids, and organ‐on‐a‐chip models are reviewed, together with future opportunities in behaviorome profiling, multi‐omics integration, personalized medicine, immune crosstalk, and multi‐organ ...

TGF-b2 induction regulates invasiveness of theileria-transformed leukocytes and disease susceptibility [PDF]

open access: yes, 2010
Theileria parasites invade and transform bovine leukocytes causing either East Coast fever (T. parva), or tropical theileriosis (T. annulata). Susceptible animals usually die within weeks of infection, but indigenous infected cattle show markedly reduced
