NLRP3 inflammasomes and skin diseases / 中华皮肤科杂志

NOD-like receptor protein 3 (NLRP3) inflammasomes play an important role in innate immunity.It can induce the maturation and release of cytokines interleukin (IL)-1β and IL-18 by activating caspase-1,and participate in a variety of host immunoinflammatory responses.Once the regulation of NLRP3 inflammasomes is unbalanced,excessive IL-1β and IL-18 may be produced,triggering a series of inflammatory diseases.NLRP3 inflammasome activation plays important roles in skin diseases such as acne,psoriasis,pyoderma gangrenosum,polymyositis/dermatomyositis and bullous pemphigoid.This review summarizes research progress in NLRP3 inflammasomes in skin diseases.

Role of skin-resident memory T cells in inflammatory response in vitiligo / 中华皮肤科杂志

Tissue-resident memory T (T RM) cells are derived from stimulated naive T cells and reside in peripheral tissues, mediating rapid immune responses of the host to similar stimuli. Although this immune response helps protect the host against local infections, long-term residence of T RM cells in the skin can lead to repeated attacks of autoimmune-related skin diseases such as vitiligo. This review summarizes the relationship between T RM cells and vitiligo as well as potential therapeutic targets.

C-terminal proteomics: strategies for characterization of protein C-terminus using MS-based techniques / 生物工程学报

C-termini of proteins often play an important role in various biological processes, such as the transcription and translation from DNA to protein and also participating in various biological regulations. The determination of protein C-terminus is so crucial because it provides not only distinct functional annotation, but also a way to monitor the proteolysis-modified proteins. Based on the biological mass spectrometry, a series of novel methods and technologies were developed both for qualitative and quantitative analyses of protein C-terminus. These methods or technologies can be applied to accurate and effective protein C-terminus profiling, including the sequences and quantitative information of C-termini, which reveals the biological function of C-termini in life's activities and provides a better understanding of the degradation of mature proteins. Combined with our research, this review highlights the improvements in C-terminal proteomics study in the past decades, including the methodologies for recognition and identification of C-terminus, as well as the enrichment strategies for protein C-terminus.
