Redirecting glucose flux during in vitro expansion generates epigenetically and metabolically superior T cells for cancer immunotherapy.

Cellular therapies are living drugs whose efficacy depends on persistence and survival. Expansion of therapeutic T cells employs hypermetabolic culture conditions to promote T cell expansion. We show that typical in vitro expansion conditions generate metabolically and functionally impaired T cells more reliant on aerobic glycolysis than those expanding in vivo.

Measurement of Λ_{b}^{0}, Λ_{c}^{+}, and Λ Decay Parameters Using Λ_{b}^{0}→Λ_{c}^{+}h^{-} Decays.

A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9  fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Two Recombinant Cytomegalovirus Antigens Formulated with the SPA14 Adjuvant System: Impact of Temperature, pH and Excipients on the Stability of each Antigen and Adjuvant Component.

By evaluating the stability profiles of each component of a vaccine candidate (antigens, adjuvants), formulation conditions to mitigate vaccine instability can be identified. In this work, two recombinant Cytomegalovirus (CMV) glycoprotein antigens (gB, Pentamer) were formulated with SPA14, a novel liposome-based adjuvant system containing a synthetic TLR4 agonist (E6020) and a saponin (QS21). Analytical characterization and accelerated stability studies were performed with the two CMV antigens, formulated with and without SPA14, under various conditions (temperature, pH, excipients).
