A claims-based retrospective cohort study shows that patients who used bisphosphonates between 01/01/2019 and 02/29/2020 had dramatically reduced odds of SARS-CoV-2 testing, COVID-19 diagnosis, and COVID-19-related hospitalizations during the initial surge of the COVID-19 pandemic in the US.

The targeted removal of legacy bisphosphonate from the jawbone by competitive equilibrium therapy not only elucidated the pathological mechanism of bisphosphonate-related osteonecrosis of the jaw (BRONJ) but also established a highly translatable therapeutic option for BRONJ.

As well as preventing bone loss, bisphosphonate drugs may boost early immune responses in the lung by acting directly on alveolar macrophages that form one of the first lines of defence against infection.

Identification of a transporter complex comprised of SLC37A3 and ATRAID is required for nitrogen-containing bisphosphonates to enter the cytosol from lysosomes and exert their therapeutic effects on bone.

Increasing PI(4,5)P2 on a sub-second timescale using a novel, membrane-permeant UV activatable PI(4,5)P2 molecule augments exocytosis which requires the PI(4,5)P2 interacting exocytotic proteins Munc13-2 and synaptotagmin-1.

The loss of miRNA-27a stimulates osteoclast-mediated bone resorption but does not affect osteoblast-mediated bone formation, leading to the development of osteoporosis in mice.

Drugs called bisphosphonates are used to treat a range of bone diseases, but how do they reach the enzymes that are their target?

The prolactin receptor, Janus kinase 2, and PI(4,5)P₂ form a co-structure with the membrane resulting in orientations with different accessibility fixing the disordered juxtamembrane domain of the receptor in an extended structure.

The concept of compound fracture risk is redefined to combine the risk that an individual will sustain a fracture and the risk of mortality once the fracture has occurred.

A mathematical model of osteoporosis explains why the sequence of osteoporosis medications matters for short-term and long-term treatment success.
