Chimeric antigen receptors (CARs): (a) anatomy and evolution of CAR design, and (b) CAR T cells recognize specific antigens on cancer cell surface and trigger T-cell–mediated killing.

Study design and experimental workflow. A two-phased strategy was employed to identify and characterize candidate protein biomarkers of ARV infection from NPL samples collected from participants in four experimental ARV challenge cohorts. For phase 1 discovery analysis, four NPL pools were prepared from H3N2 #1 cohort and analyzed using unbiased 2D-LC-MS/MS. The numbers of subject (N) with samples included in each pool are shown (Uninf = uninfected individuals; Inf = infected individuals; BL = baseline; T = time of maximal symptoms). For phase 2, the original and three additional independent challenge cohorts were assayed by targeted MRM...

(a–c) Dose response effects on the median lifespan of select C. briggsae strains after treatment with chemicals that exhibited strong positive effects on the C. elegans strains. Dosing was performed only on strains that failed to respond positively in the initial tests (single dose experiments), as we did not attempt to identify peak responses, instead we only sought to identify whether positive effects could be obtained by altering doses. Chemical doses were chosen to center around the effective dose identified for C. elegans strains and were sometimes expanded after preliminary rounds of testing. ThT exhibited a positive effect on strain JU1348 at 25 μM, but was profoundly toxic to all strains at and above 100 μM
