Non-specific lipid-transfer proteins: Allergen structure and function, cross-reactivity, sensitization, and epidemiology.
Discovered and described 40 years ago, non-specific lipid transfer proteins (nsLTP) are present in many plant species and play an important role protecting plants from stressors such as heat or drought. In the last 20 years, sensitization to nsLTP and consequent reactions to plant foods has become a...

In the last 20 years, sensitization to nsLTP and consequent reactions to plant foods has become an increasing concern. The aim of this paper is to review the evidence for the structure and function of nsLTP allergens, and cross-reactivity, sensitization, and epidemiology of nsLTP allergy.

In some populations, Pru p 3 is the primary and sole sensitizing allergen, but many are poly-sensitised both to botanically un-related nsLTP in foods, and non-food sources of nsLTP such as Cannabis sativa, Platanus acerifolia, (plane tree), Ambrosia artemisiifolia (ragweed) and Artemisia vulgaris (mugwort).

| description |
Discovered and described 40 years ago, non-specific lipid transfer proteins (nsLTP) are present in many plant species and play an important role protecting plants from stressors such as heat or drought. In the last 20 years, sensitization to nsLTP and consequent reactions to plant foods has become an increasing concern. The aim of this paper is to review the evidence for the structure and function of nsLTP allergens, and cross-reactivity, sensitization, and epidemiology of nsLTP allergy. A Task Force, supported by the European Academy of Allergy & Clinical Immunology (EAACI), reviewed current evidence and provide a signpost for future research. The search terms for this paper were "Non-specific Lipid Transfer Proteins", "LTP syndrome", "Pru p 3", "plant food allergy", "pollen-food syndrome". Most nsLTP allergens have a highly conserved structure stabilised by 4-disulphide bridges. Studies on the peach nsLTP, Pru p 3, demonstrate that nsLTPs are very cross-reactive, with the four major IgE epitopes of Pru p 3 being shared by nsLTP from other botanically related fruits. These nsLTP allergens are to varying degrees resistant to heat and digestion, and sensitization may occur through the oral, inhaled or cutaneous routes. In some populations, Pru p 3 is the primary and sole sensitizing allergen, but many are poly-sensitised both to botanically un-related nsLTP in foods, and non-food sources of nsLTP such as Cannabis sativa, Platanus acerifolia, (plane tree), Ambrosia artemisiifolia (ragweed) and Artemisia vulgaris (mugwort).
