: Long-term survival of T lymphocytes in quiescent state is essential to maintain their cell numbers in secondary lymphoid organs and in peripheral circulation. In the BioBreeding diabetes-prone strain of rats (BB-DP), loss of functional GIMAP5 (GTPase of the immune associated nucleotide binding protein 5) results in profound peripheral T lymphopenia. This discovery heralded the identification of a new family of proteins initially called Immune-associated nucleotide binding protein (IAN) family. In this review we will use 'GIMAP' to refer to this family of proteins. Recent studies suggest that GIMAP proteins may interact with each other and also be involved in the movement of the cellular cargo along the cytoskeletal network. Here we will summarize the current knowledge on the characteristics and functions of GIMAP family of proteins.

Dr. Rolf M. Schwiete Center for Limbal Stem Cell and Congenital Aniridia Research, Saarland University, Saar, Germany.
Purpose: Our aim was to examine the expression of PAX6 and keratocyte-specific markers in human limbal stromal cells (LSCs) in congenital aniridia (AN) and in healthy corneas, .
Methods: Primary human LSCs were extracted from individuals with aniridia (AN-LSCs) ( = 8) and from healthy corneas (LSCs) ( = 8). The cells were cultured in either normal-glucose serum-containing cell culture medium (NGSC-medium) or low-glucose serum-free cell culture medium (LGSF-medium).

This perpective delves into the emerging field of matere bonds, a novel type of noncovalent interaction involving group 7 elements such as manganese, technetium, and rhenium. Matere bonds, a new member of the σ-hole family where metal atoms act as electron acceptors, have been shown experimentally and theoretically to play significant roles in the self-assembly and stabilization of supramolecular structures both in solid-state and solution-phase environments. This perspective article explores the physical nature of these interactions, emphasizing their directionality and structural influence in various supramolecular architectures.

SGLT2 inhibitors are a family of drugs that were developed to treat diabetes mellitus. In randomized controlled trials, SGLT2 inhibitors seem to prevent kidney deterioration in patients with nephropathies, both diabetic and non-diabetic. However, in contrast to biochemical/physiological results (proteinuria and serum creatinine levels) that improve in all studies, the clinical results (all-cause mortality, cardiovascular death, need for dialysis, or renal transplant) do not consistently improve.

Family with sequence similarity 20 C (FAM20C) is a Golgi protein kinase that phosphorylates the serine residue in the S-x-E/pS motif of target proteins. FAM20C phosphorylates most secreted proteins, which play important roles in multiple biological processes, including cancer progression, biomineralization, and lipid homeostasis. Numerous studies have documented the potential contribution of FAM20C to the growth, invasion, and metastasis of glioma, breast cancer, and other cancers, as well as to the mineralization process of teeth and bone.
