OMIP 076: High-dimensional immunophenotyping of murine T-cell, B-cell, and antibody secreting cell subsets

There is now considerable evidence demonstrating that both prenatal and postnatal exposure to particular classes of microbial stimuli can provide beneficial signals during early life immune development, resulting in the protection against future inflammatory disease.

Metabolic dysfunction induced by a high-fat diet modulates hematopoietic stem and myeloid progenitor cells in brown adipose tissue of mice

Brown adipose tissue (BAT) may be an important metabolic regulator of whole-body glucose. While important roles have been ascribed to macrophages in regulating metabolic functions in BAT, little is known of the roles of other immune cells subsets, particularly dendritic cells (DCs). Eating a high-fat diet may compromise the development of hematopoietic stem and progenitor cells (HSPCs)-which give rise to DCs-in bone marrow, with less known of its effects in BAT. We have previously demonstrated that ongoing exposure to low-dose ultraviolet radiation (UVR) significantly reduced the 'whitening' effect of eating a high-fat diet upon interscapular (i) BAT of mice.

Transplacental Innate Immune Training via Maternal Microbial Exposure: Role of XBP1-ERN1 Axis in Dendritic Cell Precursor Programming

We recently reported that offspring of mice treated during pregnancy with the microbial-derived immunomodulator OM-85 manifest striking resistance to allergic airways inflammation, and localized the potential treatment target to fetal conventional dendritic cell (cDC) progenitors. Here, we profile maternal OM-85 treatment-associated transcriptomic signatures in fetal bone marrow, and identify a series of immunometabolic pathways which provide essential metabolites for accelerated myelopoiesis.

A subset of patients with systemic lupus erythematosus fails to degrade DNA from multiple clinically relevant sources.

Patients with systemic lupus erythematosus (SLE) have a decreased ability to clear cell remnants and multiple deficiencies in the ability to degrade cellular...

Genome-wide DNA methylation profiling identifies a folate-sensitive region of differential methylation upstream of ZFP57-imprinting regulator in humans

This study identified that expsoure to folate has effects on the regulation of DNA methylation during fetal development.

The complement system in systemic lupus erythematosus: An update

The complement system plays a major role in the autoimmune disease, systemic lupus erythematosus (SLE). This review highlights the many roles of complement for

Neonatal antigen-presenting cells are functionally more quiescent in children born under traditional compared with modern environmental conditions

One explanation for the high burden of allergic and autoimmune diseases in industrialized countries is inappropriate immune development under modern...

Defective aeroallergen surveillance by airway mucosal dendritic cells as a determinant of risk

A hallmark of atopic asthma is development of chronic airways hyper-responsiveness (AHR) that persists in the face of ongoing exposure to perennial...

Virus infection and allergy in the development of asthma: What is the connection?

Information is accumulating which implicates airway inflammation resulting from respiratory viral infections, acting against a background of atopy.

Inert 50-nm Polystyrene Nanoparticles That Modify Pulmonary Dendritic Cell Function and Inhibit Allergic Airway Inflammation

Nanoparticles are being developed for diverse biomedical applications, but there is concern about potential to promote inflammation, particularly in the lungs.
