Chief, Genetics and Pathogenesis of Allergy Section, LAD

Major Areas of Research

  • Investigation of defects in T-cell receptor signaling and repertoires
  • Clinical and pathophysiologic analysis of patients with known genetic diseases associated with atopy
  • Search for novel genetic diseases associated with atopy
 

Program Description

The Genetics and Pathogenesis of Allergy Section is a basic, translational, and clinical lab focused on understanding the immunology of atopic disease through study of patients with genetic diseases associated with atopic manifestations, patients with immune deficiency and atopy, and patients with severe atopic dermatitis. Through studies of patients and mouse models of their diseases, we hope to gain better insights into the mechanisms of immunodysregulation that lead to atopic inflammatory disease, rare and common.

Josh Milner and an NIAID research team have found that wet wrap therapy combined with education on long-term skin care can dramatically improve the lives of children with severe eczema.

Search for novel genetic diseases associated with atopy

The section is also centrally focused on defining and understanding new genetic diseases of atopy in order to find novel pathways in the pathogenesis of allergy from these unique diseases. Patients with histories highly suggestive of a familial/syndromic inheritance of their allergic symptomps—from urticarial to atopic dermatitis—are studied, their DNA sequenced, and their cell biology elucidated. One example is PLCG2-associated antibody deficiency and immune dysregulation (PLAID), which we recently described. Patients with PLAID have cold urticaria, atopy, immune deficiency, and autoimmunity. Research is ongoing into the pathophysiology of PLAID and into the role of the PLCG2 and its pathway in other related disorders.

Analysis of patients with known genetic diseases associated with atopy

Via the study of selected genetic diseases that have allergic symptoms as an associated manifestation, we hope to derive lessons in the pathophysiology of atopy from the known affected pathways. Examples of diseases studied include the autosomal dominant hyper-immunoglobulin (IgE) syndrome due to mutations in STAT3, Wiskott-Aldrich Syndrome, adenosine deaminase (ADA)-deficiency severe combined immunodeficiency disease (SCID) associated with high IgE and others.

Investigation of defects in T-cell receptor signaling and repertoires

Weak T-cell receptor (TCR)-mediated signaling of yet-undifferentiated naïve T cells can lead to inappropriate Th2 differentiation in mouse models. Insufficient TCR diversity can lead to impaired regulation of T cells by other T cells due to insufficient TCR specificity overlap of effector and regulatory populations or due to the absence of competition between T cells leading to the inappropriate emergence of weakly signaling TCRs specific for a given antigen. Our lab is developing and applying techniques to determine whether certain human disorders of atopy may be caused by defects in TCR diversity or signaling function.

Biography

Joshua Milner graduated with an S.B. in biology from the Massachusetts Institute of Technology (MIT) in 1995 and an M.D. with distinction in immunology from the Albert Einstein College of Medicine in 2000. He finished his residency in pediatrics at the Childrens National Medical Center in Washington, DC, in 2003. He was the recipient of the Pediatric Scientist Development Program Fellowship and did his fellowship in allergy and immunology at NIAID. He completed a postdoctoral fellowship with Dr. William Paul, NIAID, examining issues of mouse T-cell receptor repertoires. He was in the NIAID Clinical Research Transition Program immediately prior to being named chief of the section as a clinical tenure-track investigator in NIAID in 2009. He received tenure in 2013.
