The History of Mpox Research

Corpora non agunt nisi fixata" (agents only work when they are bound)

Prior to the mid-20th century, the field of pharmacology, while rich in empirical observation, operated with a limited understanding of the precise molecular mechanisms underpinning drug action. Many therapeutic agents were developed and utilized based on their observed physiological effects, often without a clear grasp of their cellular targets or the intricate pathways they influenced. Early pioneers like Paul Ehrlich, with his concept of "corpora non agunt nisi fixata" (agents only work when they are bound), and John Newport Langley, who...

The environment within an academic science laboratory is far more than a physical space equipped with instruments and reagents. It is a complex social ecosystem defined by its "lab culture." This culture represents the shared values, beliefs, attitudes, assumptions, and behaviors that dictate the daily functioning and interpersonal dynamics of a research group. It is the collective answer to "what we care about" within the lab, encompassing not only the pursuit of scientific knowledge but also the regard for people and relationships. For new principal investigators (PIs) or incoming lab members, this often "intangible" aspect of the laboratory environment...

The path to understanding GLP-1 and its therapeutic utility was not a direct one, but rather an incremental journey rooted in decades of endocrinological investigation. Initial explorations in the 1960s and 1970s focused on glucagon, a pancreatic hormone known to elevate blood sugar levels. During this period, researchers identified proglucagon, a larger precursor molecule that was hypothesized to yield multiple, then-unidentified, peptide hormones.

This early work on proglucagon processing set the stage for the eventual discovery of GLP-1. The "mystery of proglucagon-derived peptides" began to unfold between 1980 and 1983, when scientists successfully mapped the amino...

The dual-degree clinician-scientist, often termed a physician-scientist, represents a distinct and critical professional in the biomedical ecosystem, uniquely positioned at the confluence of direct patient care and rigorous scientific inquiry.

It is not merely a scientific pursuit but a highly regulated process designed to ensure that new medicines are both safe and effective for patient use.

The intricate relationship between a protein's linear sequence of amino acids and its resultant three-dimensional structure is a cornerstone of molecular biology, as this conformation dictates the protein's specific biological function. The challenge of accurately predicting this folded structure from the amino acid sequence alone, often referred to as the protein folding problem, has occupied researchers for over half a century, a point emphasized by Nobel Laureate Venki Ramakrishnan. The sheer complexity of this task is highlighted by the staggering number of theoretically possible conformations a protein can adopt. For instance, a relatively small protein consisting of just 100 amino...

The human gastrointestinal tract is colonized by an extraordinarily dense and diverse community of microorganisms, collectively termed the gut microbiome. This intricate ecosystem comprises trillions of bacteria, archaea, viruses, fungi, and parasites, with bacteria being the most abundant and well-studied component, encompassing over a thousand distinct species. This "microscopic world within" is primarily concentrated in the large intestine and is unique to everyone. Its initial establishment is heavily influenced by maternal factors during vaginal delivery and breastfeeding, followed by continuous modulation throughout life by factors such as diet and other environmental exposures.

The human microbiome, a complex and dynamic community of microorganisms inhabiting the human body, has emerged as a critical factor influencing various aspects of health and disease. This intricate ecosystem, comprising bacteria, archaea, fungi, viruses, and eukaryotes, resides in association with human tissues and biofluids, playing essential roles in physiological processes that extend far beyond the initial understanding of microbes as mere pathogens. These microbial communities are now recognized for their profound impact on human well-being, contributing significantly to our overall health and susceptibility to a wide range of conditions. The scientific exploration of this field has undergone a...
