A method for assessing a biological condition associated with metal metabolism in a subject, the method comprising sampling a location along a biological sample of the subject to obtain a number of ion samples. Each ion sample corresponds to a location on the biological sample, and each location represents an amount of growth of the biological sample. The obtained ions are analyzed with a mass spectrometer, thereby obtaining a plurality of traces. Each such trace represents a concentration over time of a corresponding elemental isotope of a plurality of elemental isotopes. A set of features is derived from the trace. Each feature is determined by a change in a single isotope or combination of isotopes in the plurality of traces. The set of features is input into a trained classifier to obtain a probability that the subject has the biological condition associated with metal metabolism.

Mammals rely on adaptive immunity to protect against infections and tumors, with the thymus playing a crucial role by producing T cells that target infected or cancerous cells. The thymus, however, undergoes functional decline with age, significantly impairing the immune system in the elderly. To investigate reversing this decline, compositions and methods for activation and differentiation of T cell progenitors in extrathymic tissues are disclosed that stimulate production of differentiated T cells. For example, LNP-mediated delivery of mRNAs encoding DLL-1, IL-7, and FLT3L to the liver is shown to create a temporary site for T cell maturation that enhances T cell-mediated immunity in aged mice without causing autoimmunity. This approach facilitates ectopic T cell development from hematopoietic precursors and activates dendritic cells, providing evidence that engineering adaptive immunity in vivo can effectively mitigate immune aging.
