Unraveling the role of NLRP3 inflammasome in allergic inflammation: implications for novel therapies.

Allergic diseases like asthma, allergic rhinitis and dermatitis pose a significant global health burden, driving the search for novel therapies. The NLRP3 inflammasome, a key component of the innate immune system, is implicated in various inflammatory diseases. Upon exposure to allergens, NLRP3 undergoes a two-step activation process (priming and assembly) to form active inflammasomes.

ILC2s: Unraveling the innate immune orchestrators in allergic inflammation.

The prevalence rate of allergic diseases including asthma, atopic rhinitis (AR) and atopic dermatitis (AD) has been significantly increasing in recent decades due to environmental changes and social developments. With the study of innate lymphoid cells, the crucial role played by type 2 innate lymphoid cells (ILC2s) have been progressively unveiled in allergic diseases. ILC2s, which are a subset of innate lymphocytes initiate allergic responses.

Herb-drug interactions between androgenic Chinese herbal medicines and androgen receptor antagonist on tumor growth: Studies on two xenograft prostate cancer animal models.

Our previous study revealed that Epimedii Folium (EF) and Codonopsis Radix (CNR) significantly promoted tumor growth on a subcutaneous mouse model of prostate cancer (PCa) via enhancing the mRNA and protein expressions of androgen receptor (AR), while Astragali Radix (AGR) inhibited tumor growth via suppressing the protein expression of AR.
