Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis. Immunization of B10.PL mice with the Ac1-9 peptide, the immunodominant determinant of myelin basic protein (MBP), produced a single episode of EAE followed by recovery and resistance to reinduction of disease. Using the CDR3 length spectratyping technique, we characterized the clonal composition of the Ac1-9-specific T cell repertoire from induction through onset and resolution of disease. Two clonally restricted subsets within a heterogeneous self-reactive repertoire were found in mouse lymph nodes, spleen, and spinal cord soon after immunization, before any sign of EAE. These clonotypes, designated BV8S2/BJ2S7 and BV16/BJ2S5, were present in all mice examined and thus considered public. BV8S2/BJ2S7 was found in far greater excess; was exclusively Th1 polarized; disappeared from the spinal cord, spleen, and lymph nodes concomitantly with recovery; and transferred disease to naive recipients. In contrast, BV16/BJ2S5 and numerous private clonotypes were either Th1 or Th2 and persisted following recovery. These results are consistent with the hypothesis that the public clonotype BV8S2/BJ2S7 is a driver of disease and necessary for its propagation.

Objective: To conduct a meta-analysis assessing the diagnostic performance of the node reporting and data system (Node-RADS) for detecting lymph node (LN) invasion.
Method: We performed a systematic literature search of online scientific publication databases from inception up to July 31, 2024. We used the quality assessment of diagnostic accuracy studies-2 (QUADAS-2) to assess the study quality, and heterogeneity was determined by the Q-test and measured with I statistics.

Background: Gastric cancer poses a major diagnostic and therapeutic challenge. Improved visualization of tumor margins and lymph node metastases with tumor-specific fluorescent markers could improve outcomes.
Methods: To establish orthotopic models of gastric cancer, one million cells of the human gastric cancer cell line, MKN45, were suspended in 50 μl of equal parts PBS and Matrigel and injected into the nude mouse stomach with a 29-gauge needle.

Objective: This research was undertaken to identify risk factors for the involvement of sentinel lymph nodes (SLNs) in cases of endometrial cancer.
Methods: From February 2016 to April 2021, the cases of 874 women with endometrial cancer treated with the SLN algorithm at 11 institutions were analyzed in this retrospective study. Clinical and pathologic data were reviewed, and logistic regression was applied to identify predictive factors for SLN involvement.

Objective: The aim of this study was to examine the role of pre-sacral sentinel lymph nodes (SLNs) in patients with uterine cancer.
Methods: This retrospective cohort study includes patients with endometrial or cervical cancer who underwent minimally invasive indocyanine green SLN mapping at the Bern University Hospital from December 2012 to December 2022. A complete ultra-staging of the SLNs was performed in all cases.
