Project description:Breastfeeding provides important immunological benefits to the neonate, but how different immunoactive components in breastmilk contribute to immunity remains poorly understood. Here, we characterized human breastmilk T cells using single cell RNA sequencing and flow cytometry. Breastmilk contained predominantly memory T cells with immune response signaling, proliferation and an effector Th1/cytotoxic profile with high cytokine production capacities. High activation markers were balanced by an enriched Treg population and immune regulatory markers in conventional memory T cells. Gene and surface expression of tissue-residency markers indicated that breastmilk T cells represent tissue-adapted rather than circulatory T cells. In addition, breastmilk T cells had a broad homing profile and higher activation markers in these migratory subsets. The partly overlapping transcriptome profile between breastmilk and breast tissue T cells, particularly cytotoxic T cells, might support a role in local immune defense in the mammary gland. However, unique features of breastmilk, such as regulatory T cells, might imply an additional role in neonatal immune defense. We found some correlations between the breastmilk T-cell profile and clinical parameters, most notably with maternal and household factors. . Together, our data suggest that breastmilk contains an adapted T cell population that exerts their function in specific tissue-sites.

Project description:Longitudinal disease-associated gut microbiome differences in infants with early food allergic manifestations

Project description:The prevalence of respiratory allergy in children is increasing. Epigenetic changes (e.g. DNA methylation) are plausible underlying molecular mechanisms. Longitudinal birth cohorts are instrumental to study the relation between early-life environmental factors and the development of complex diseases. Our AXA Research Fund and Cefic-LRI supported project explores the hypothesis that chemical exposures during pregnancy can influence the immune system and development of allergy in children. Questionnaire data, as well as cord blood, plus blood and saliva samples at age 11 years, were collected in substudies of two longitudinal birth cohorts in Belgium (FLEHS1 & FLEHS2) and analyzed with Illumina Methylation 450K BeadChips as well as gene targeted iPLEX MassArrays analysis. The project aims to answer the following questions: 1) can we identify specific changes in epigenetic modifications on DNA from allergic compared to not-allergic children; 2) are these allergy-related epigenetic changes a result of chemical exposure during pregnancy; and 3) did the early life exposures leave an epigenetic “mark” that is maintained through childhood. If chemicals exposures and resulting predictive markers of allergic diseases can be detected early, prevention strategies, particularly in children or before pregnancy, could be developed.

Project description:Bioactive RNA in Maternal Breastmilk

Project description:The nutrition contents of breastmilk can transfer into the blood of neonates, directly participating in neonatal immune response. The alternations of the components of breastmilk under the context of viral infection not only reflect the physiological changes in mothers but also affect neonatal immunity and metabolism via breastfeeding. There has been no report to demonstrate the changes of bioactive components in breastmilk of puerperant women with COVID-19. Thereby, we attempted to answer the important questions whether breastmilk production is affected by COVID-19 and whether breastfeeding is still a safe or recommended operation for puerperant women with COVID-19.

Project description:Background Atopic diseases, resulting from hypersensitivity to a wide variety of allergens, affect 10-20% of the population. Immunotherapy is an effective treatment for atopic diseases, but its mechanisms are not fully understood. Objective We studied gene expression profiles in the peripheral blood mononuclear cells and examined whether the individuals with allergic rhinitis have a unique gene expression profile and how the immunotherapy affect the gene expression profiles. Method We used cDNA microarray and â??Expression Analysis Systemic Explorerâ?? to examine the gene expression profiles in the peripheral blood mononuclear cells of atopic subjects and other groups. Results We identified a highly conserved gene expression profile in atopic subjects that permitted their accurate segregation from control or autoimmune subjects. A major feature of this profile was the under-expression of a variety of genes that encode proteins required for apoptosis and over-expression of genes that encode proteins critical for stress responses and signal transduction. We also identified 563 genes that can segregate individuals with allergic rhinitis based upon receipt of immunotherapy. Conclusion There is a highly conserved gene expression profile in the peripheral blood mononuclear cells of individuals with allergic rhinitis. This profile can be used to identify individuals with allergic rhinitis and to evaluate responses to immunotherapy. Quantitative endpoints, such as gene expression, may assist clinicians faced with clinical decisions in the diagnosis of patients and the evaluation of response to therapy. The knowledge of the possible genetic basis for immunotherapy efficacy may also lead to novel therapeutic approaches for atopic diseases.

Project description:In the first decade of life, high-asthma risk urban children develop stable phenotypes of respiratory health versus disease that link early life environmental exposures to childhood allergic sensitization and asthma. Moreover, unique patterns of nasal gene expression demonstrate how specific molecular pathways underlie distinct respiratory phenotypes, including allergic and non-allergic asthma.

Project description:Peanut allergy is increasingly prevalent among children in the United States and other industrialized countries and is now estimated to affect approximately 2% of children. While there are currently no approved treatment options, peanut allergy usually persists into adulthood, can be life-threatening, and accounts for most deaths related to food allergy. Here, we track peanut-reactive CD4+ T effector (pTeff) cells using the CD154 up-regulation assay. We found that CRTH2+ pTeff cells and CCR6+ pTeff cells represent two mutually exclusive, non-overlapping cellular and molecular entities involved in food allergic diseases.
