Likewise, in recent years, attention has been focused on different strategies for the discovery and development of new selectivity ligands against transforming growth factor beta-activated kinase 1 (TAK1), a potential therapeutic target for gout. Therefore the insight on human XO structure and TAK1 provides a clue into protein-ligand interactions and provides the basis for molecular modeling and structure-based drug design. In this review, we briefly introduce the clinical characteristics, the development of crystal, inhibitors, and crystal structure of XO and TAK1 protein. In this review, we briefly introduce the clinical characteristics, the development of crystal, inhibitors, and crystal structure of XO and TAK1 protein. Systemic lupus erythematosus (SLE) has a variable natural history and clinical characteristics. To evaluate the clinical and immunological characteristics, and to assess the disease accrual of an Egyptian SLE cohort. The study included 569 SLE patients who were collected from three different centers; demographic, laboratory data, cumulative manifestations, and comorbidities were assessed (characteristics at the time of diagnosis were recorded retrospectively, while current clinical data were recorded cross-sectionally). Evaluation of disease activity was done using Systemic Lupus Erythematosus Disease Activity Index score (SLEDAI) and damage by Systemic Lupus International Collaborative Clinics/American College of Rheumatology Damage Index (SDI). The median age of patients at disease onset was 25.0±10.5 years, the median of disease duration was 4.0 (6.5) years, female to male ratio was (12.51), and the median SLEDAI was 12.0±14.0. Family history of SLE was noticed in 4%. Antinuclear antibody was positsly reported data. Arthritis is the most common presenting symptom, while alopecia is the most frequent clinical finding, and h
