Welcome

An introduction from Professor Valerie Verhasselt, Director of the Larsson Rosenquist Foundation Centre for Immunology and Breastfeeding

Vision

Making human milk the gold standard for children's immune health.

By this, we mean ensuring that:

  • Human milk promotes child health worldwide
  • Where appropriate, preventive and therapeutic strategies for children are inspired by human milk

Mission

Build a holistic understanding of how breastfeeding practices and human milk composition influence healthy immune development.

This knowledge will enable healthcare providers to make recommendations to parents to improve child health worldwide.

Our research

Why translational research into breastfeeding if we already know that human milk is the best?

  • By learning from human milk, we can revolutionize how we care for newborns, offering interventions that are truly aligned with their developmental needs.

    Today, most treatments for newborns are the same as for adults, i.e. mainly the dose is modified. However, we are learning more every day about the differences between a newborn and an adult, and breast milk has known this for a long time. By studying the immunology of breastfeeding,  our research has shown that human milk may know the best way to promote mucosal immunity in infants.

    (Macchiaverni et al., 2024; van den Elsen et al., 2022)

  • To provide advice to mothers and health professionals to maximise the chances of disease prevention through breastfeeding.

    From pollutants to infection and dietary habits, the constituents of breast milk encapsulate a snapshot of the maternal environment, providing infants with a preview of the world they will inhabit. By investigating how human milk composition influences healthy immune development, we are paving the way for personalized advice that can help mothers maximise disease prevention through breastfeeding. Our research has suggested that consuming allergens while breastfeeding may be the best way to prevent allergies in children. Ongoing clinical trials led by our collaborator A/Prof Debbie Palmer should soon tell us whether this suggestion can become a recommendation.

  • Provide strong evidence to invest in breastfeeding support.
    Despite the World Health Organization's (WHO) guidelines promoting early initiation and exclusive breastfeeding, at least a third of newborns worldwide aren't benefiting from this optimal feeding practice, due to late initiation of breastfeeding or the administration of formula "supplements" that replace colostrum intake. We already know that colostrum is essential for reducing neonatal mortality in low resources settings. Our ongoing research will establish the importance of colostrum in preventing allergies, parasitic infections, stunted growth and much more.

Our research programmes

Establishing the role of human milk in healthy child development

A healthy immune system mounts appropriate and efficient immune responses that protect us from pathogens, cancer, allergies, autoimmunity, inflammatory bowel disease and malnutrition.

The objective of our research is to gain a deeper understanding of how colostrum feeding and human milk composition support the child’s developing immune system, and how it contributes to shaping the immune trajectory and lifelong health.

Figure description: Specifically, we have two main programmes: One investigating the benefits of colostrum feeding on child long term health and the other on how we can target breastmilk composition to maximize child health.

What are our main discoveries?

  • Colostrum is required for gut immune development and successful anti-helminth defences

    Colostrum is required for gut immune development and successful anti-helminth defences (Rekima et al., 2024)

    Worldwide, more than 1.5 billion people, or 25% of the world's population, are infected with soil-transmitted helminths, and infected children are nutritionally and physically impaired, with major societal and economic consequences.

    In a unique preclinical model of colostrum deprivation, Rekima et al (2024) showed that colostrum is essential for the expansion of key immune cells in the gut for helminth infection control (type 2 innate lymphoid immune cells). Microbiota was not required for this. We also showed in a proof-of-concept birth cohort in Uganda that providing the first drops of colostrum to a newborn is associated with a major decrease in helminth infections in childhood.

    In conclusion, our study provides new evidence on how to reduce a major disease burden, helminth infection: promote colostrum feeding! This study highlights that we can learn from colostrum to design interventions tailored to neonates that promote health (and go beyond microbiota intervention).

  • Colostrum feeding may be critical to reducing the burden of undernutrition

    Current strategies for undernutrition prevention focus on intervention at the time of complementary feeding, while stunting often starts earlier.  We hypothesised that the crosstalk between colostrum and the gut microbiota is critical for healthy growth, based on the timing of colostrum intake when the gut gets colonized with bacteria, and on its content of high levels of microbiota-shaping compounds. To address this question, we developed a preclinical model of colostrum deprivation. Experiment was performed in both SPF and germ-free mice. Van den Elsen et al demonstrated that the absence of colostrum feeding at birth decapitated the phenotype of chronic undernutrition, with growth hormone resistance, systemic inflammation, low leptin, high lipids. This phenotype was associated with significantly change in the alpha and beta diversity if the gut microbiota. However, we reproduced the same phenotype in colostrum deprived germ-free mice. Our work will stimulate research to identify which factors in colostrum promote growth and open new avenues for promoting healthy growth in vulnerable newborns, such as for preterm who are often fed (mature) donor human milk instead of mother’s own colostrum and milk.

  • Colostrum and IgA are most effective in protecting against COVID-19 infection

    Newborns will remain the only immunologically naïve and vulnerable population as long as SARS-CoV-2 continues to circulate and infect us, probably for a long time.  We therefore need a specific approach to COVID-19 prevention in newborns. In a birth cohort from Spain, Macchiaverni et al., showed that the highest protective activity of human milk against COVID-19 was found in the colostrum of infected mothers and depended on anti-SARS-CoV-2-specific IgA. Our findings support the need to evaluate maternal mucosal COVID-19 vaccination to promote IgA secretion at mucosal sites, including breast milk, for best child protection. They highlight the importance of promoting support for successful breastfeeding initiation. Despite WHO guidelines, a high proportion of newborns are still not fully colostrum-fed, especially if their mothers are infected with COVID-19.

  • Pathogen antigen shedding in breast milk to vaccinate infants

    Based on our observation that some antigens in maternal milk stimulate a long-term immune response in the offspring (Baiz et al., 2017; Macchiaverni et al., 2014; Rekima et al., 2020), we proposed that the transfer of microbial antigens in breast milk may be the most efficient way to vaccinate infants (Marchant et al., 2017; van den Elsen et al., 2022; Verhasselt, 2015). Pathogen in breast milk would be the perfect attenuated vaccine or pathogens antigens would be surrounded by adjuvants designed for the developing infant mucosa. We proved the premises of this hypothesis in the context of Malaria by showing that malaria antigens are found in human milk (van den Elsen, et al. 2022).

  • Educating the immune system through breast milk for allergy prevention

    In 2008, we challenged the paradigm of allergen avoidance for allergy prevention and demonstrated that egg allergen shedding in maternal milk would educate the infant immune system and decrease egg allergy susceptibility (Verhasselt et al., 2008). We confirmed this in a birth cohort study (Verhasselt et al., 2020). We further elucidated the factors required to increase allergy prevention by allergen shedding in breastmilk such as Vitamin A (Turfkruyer et al., 2016) and TGF-beta in breastmilk (Rekima et al., 2017) or maternal immunization (Adel-Patient et al., 2020; Mosconi et al., 2010). Recently, we have uncovered an unexpected risk factor for respiratory but also food allergy: respiratory house dust mite allergens in breast milk (Baiz et al., 2017; Macchiaverni et al., 2014; Rekima et al., 2020). Our recent review in the first-ranked journal in Allergy (JACI) highlights the importance of allergens in breast milk for immune system education (Macchiaverni et al., 2021). This knowledge will guide infant-tailored preventive approaches to efficiently decrease the burden of allergy (Macchiaverni et al., 2021).

Our priorities in the next 5 years

  1. Target vulnerable populations
  2. Bring knowledge on the importance of breastfeeding in healthy skin development
  3. Promote allergy prevention through Breastfeeding
  4. Prioritize our partnerships with Asia

Prof Valerie Verhasselt

Director of the LRF-Centre for Immunology and Breastfeeding

My passion is to learn from Nature to find the best solutions to promote healthy immune development. With a background in Internal Medicine and more than 20 years of research in Immunology, I want to put the mother-child dialogue through breast milk at the heart of understanding how to reduce the burden of child disease in both high and low-income countries, including allergies, malaria, worm infections, and growth failure. I strongly value creativity and discovery research. Not having a specific goal allows you to be completely open, discover what you did not expect, and marvel at it. And it's in this sense of wonder and freedom of mind that the most beautiful ideas are born, ideas that, without meaning to, can change the world. Importantly, as a Team leader, it is a source of immense gratification to contribute to the empowerment of my team members, to make them aware of their huge potential and to see them blossom.
