A recombinant protein rLZ-8, originally extracted from Ganoderma lucidum, ameliorates OVA-induced lung inflammation by regulating Th17/Treg balance.

Asthma is one of the most common chronic and inflammatory respiratory diseases, which is estimated to affect 1-10% of the population in different regions across the world. Previous studies have shown that recombinant Ling-Zhi 8 (rLZ-8), an immunoregulatory protein originally extracted from Ganoderma lucidum, plays multiple roles in regulating murine immune cells, including T cells. Here, we examined whether rLZ-8 would ameliorate pulmonary inflammation in a model of asthma-like mice.
