This represents a conundrum in that ATP-driven cellular functions only require micromolar (μM) values. Considering that nature is ordinarily conservative in the generation of high-energy phosphatic metabolites such as ATP, a potential major role for ATP has been completely overlooked and may be of paramount importance because ATP is a hydrotrope. In all phylogenetic domains, reports have established that the excessively high mM concentration of ATP is present in studies of eukaryotic cellular and tissue homogenates, living tissues, and a living organ as well as archaeotic and prokaryotic organisms. These ATP concentrations are also present in contemporary relatives of microorganisms having progenitors existing in the Precambrian Era. This feature is fundamental to cell biology across taxonomic domains. These features are interpreted as serving a foundational molecular function for maintaining organismal homeostasis.

Signals received from antigen-presenting cells (APCs) stimulate Tregs to dampen inflammation. Almost all tumors are characterized by a pathological abundance of immune suppression in their microenvironment. Conversely, the lack thereof proves detrimental to immunological disorders. Achieving a balanced expression of Tregs in relation to other immune compartments is important in establishing an effective and adaptable immune tolerance towards cancer cells and autoantigens.

Chromomeres were observed in partially decondensed chromosomes and interphase chromatin as ~100 nm globular structures. They were thought to consist of loops of chromatin fibres attached at their bases to a central protein core. However, Hi-C and other related methods led to a new concept of chromatin organization in the nuclei of higher eukaryotes, according to which nucleosomal fibrils themselves determine the spatial configuration of chromatin in the form of topologically associating domains (TADs), which are formed by a loop extrusion process and are regions whose DNA sequences preferentially contact each other. Somatic macronuclei of ciliates are transcriptionally active, highly polyploid nuclei. A feature of macronuclei is that their genome is represented by a large number of \"gene-sized\" (~1-25 kb) or of \"subchromosomal\" (~50-1700 kb) size minichromosomes. The inactive macronuclear chromatin of \"subchromosomal\" ciliates usually looks like bodies 100-200 nm in size.
