Multi‐omic profiling reveals immune cell priming signature linked to lupus prognosis

Arthritis &Rheumatology, Accepted Article.
Objective Systemic lupus erythematosus (SLE) is a multi‐organ disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.

Pituitary-Gonad Relationships in Weight Selected Lines Differing in Sexual Maturity

Poultry Science, 1968
Abstract IT has been established that there is an interaction between the secretions of the gonad and the anterior pituitary. The gonadotropic content of the anterior pituitary of pullets at various levels of egg production has been studied in several laboratories (Phillips, 1942; Nakajo and Imai, 1957).
