Mast cell –sensory neuron crosstalk in allergic diseases
Mast cells (MCs) are tissue-resident immune cells, well-positioned at the host-environment interface for detecting external antigens and playing a critical role in mobilizing innate and adaptive immune responses. Sensory neurons are afferent neurons innervating most areas of the body but especially in the periphery, where they sense external and internal signals and relay information to the brain. The significance of MC –sensory neuron communication is now increasingly becoming recognized, especially because both cell types are in close physical proximity at the host-environment interface and around major organs of the b...

Navigating the blurred path of mixed neuro-immune signaling
Evolution has created complex mechanisms to sense environmental danger and protect tissues, with the nervous and immune systems playing pivotal roles. These systems work together, coordinating local and systemic reflexes to restore homeostasis in response to tissue injury and infection. By sharing receptors and ligands, they influence the pathogenesis of various diseases. Recently, a less explored aspect of neuro-immune communication has emerged: the release of neuropeptides from immune cells and cytokines/chemokines from sensory neurons.

A quantitative systems pharmacology workflow toward optimal design and biomarker stratification of atopic dermatitis clinical trials
Atopic dermatitis (AD) is a chronic inflammatory condition of the skin characterized by recurrent eczematous lesions and intense itch that can profoundly impair quality of life.1-6 The pathophysiology of AD is complex and involves local and systemic immune dysregulation, genetic susceptibility, environmental factors, and microbiome effects.7,8 AD is a heterogeneous disease that encompasses a variety of endotypes and phenotypes (see the work cited in Facheris et  al9). The road to novel AD therapeutics10 is tortuous due to a combination of 2 factors: (Source: Journal of Allergy and Clinical Immunology)

The Immune System in Neurological Diseases: What Innate-like T Cells have to Say
The immune system classically consists of two lines of defense: innate and adaptive, both of which interact with one another effectively to protect us against any pathogenic threats. Importantly, there is a diverse subset of cells known as innate-like T cells that act as a bridge between the innate and adaptive immune systems and are pivotal players in eliciting inflammatory immune responses. A growing body of evidence has demonstrated the regulatory impact of these innate-like T cells in central nervous system (CNS) diseases, and that such immune cells can traffic into the brain in multiple pathological conditions, which ...

Epithelial-neuronal-immune cell interactions: implications for immunity, inflammation, and tissue homeostasis at mucosal sites
The epithelial lining of the respiratory tract and intestine provides a critical physical barrier to protect host tissues against environmental insults including dietary antigens, allergens, chemicals, and microorganisms. In addition, specialized epithelial cells directly communicate with hematopoietic and neuronal cells. These epithelial-immune and epithelial-neuronal interactions control host immune responses and have important implications for inflammatory conditions associated with defects in the epithelial barrier, including asthma, allergy, and inflammatory bowel diseases (IBD).

Update on Asthma Biology
This is an exciting time to be conducting asthma research. The recent development of targeted asthma biologics has validated the power of basic research to discover new molecules amenable to therapeutic intervention. Advances in high throughput sequencing are providing a wealth of “-omic” data about genetic and epigenetic underpinnings of asthma, as well as new cellular interacting networks and potential endotypes in asthma. Airway epithelial cells have emerged not only as key sensors of the outside environment, but also as central drivers of dysregulated mucosal immune r esponses in asthma.

Basophils are important for development of allergic skin inflammation
Atopic dermatitis (AD) is the most common skin inflammation in infants and young children. It is characterized by intense itching, skin barrier defects, epidermal hyperplasia, dermal infiltration by T cells and eosinophils, and type 2 –dominated local immune response, evidenced by increased cutaneous expression of type 2 cytokines and eosinophilia. In addition, AD patients exhibit elevated levels of serum IgE and IgE antibodies to environmental and food allergens.1,2 (Source: Journal of Allergy and Clinical Immunology)

Rethinking PIDs: Why the distinction between primary and secondary immune disorders is more frequently relevant than that between inborn and acquired errors of immunity
Clinical immunologists, pediatricians, and adult specialists with various subspecializations around the world are used to classify and manage patients with immune deficiencies and immune dysregulation according to their gene defect, if available, and classifications such as the International Union of Immunological Societies (IUIS) classification of inborn errors of immunity (IEIs)1,2 and the working definitions for making a clinical diagnosis of the European Society for Immunodeficiencies.3 The tables produced by these societies bear an enormous clinical and educational value, being based both on categories of immunologic ...
