Objective: To investigate safety and explore efficacy of efgartigimod (ARGX-113), an anti-neonatal Fc receptor immunoglobulin G1 Fc fragment, in patients with generalized myasthenia gravis (gMG) with a history of anti-acetylcholine receptor (AChR) autoantibodies, who were on stable standard-of-care myasthenia gravis (MG) treatment. Methods: A phase 2, exploratory, randomized, double-blind, placebo-controlled, 15-center study is described. Eligible patients were randomly assigned (1:1) to receive 4 doses over a 3-week period of either 10 mg/kg IV efgartigimod or...

Macroimmunology: the drivers and consequences of spatial patterns in wildlife immune defense

Daniel Becker, Gregory Albery, Maureen Kessler, Tamika Lunn, Caylee Falvo, Gábor Czirják, Lynn Martin & Raina Plowright
1. Spatial variation in parasite pressure, abiotic and biotic conditions, and anthropogenic factors can all shape immune phenotypes across spatial scales. Identifying the most important spatial drivers of immunity could help preempt infectious disease risks, especially in the context of how large-scale factors such as urbanization affect defense by changing environmental conditions. 2. We provide a synthesis of how to apply macroecological approaches to the study of ecoimmunology (i.e., macroimmunology). We first review spatial factors...

Data from: Effects of forestry-driven changes to groundcover and soil moisture on amphibian desiccation, dispersal, and survival

Christopher J.E. Haggerty, Thomas L. Crisman & Jason R. Rohr
Over 80% of amphibian species that are declining are forest dependent. Forestry practices are a major cause of forest alterations globally, and it is well documented that clearcutting can contribute to amphibian declines. However, there might be adverse effects of forestry practices other than clearcutting. For example, planting overstory trees in rows (plantations) can change groundcover microhabitats and soil moisture levels, but the effects of this common practice on amphibian populations are not well studied....

The effects of body mass on immune cell concentrations of terrestrial mammals

Cynthia J. Downs, Ned A. Dochtermann, Ray Ball, Kirk C. Klasing & Lynn B. Martin
Theory predicts that body mass should affect the way organisms evolve and use immune defenses. We investigated the relationship between body mass and blood neutrophil and lymphocyte concentrations among 250+ terrestrial mammalian species. We tested whether existing theories (e.g., Protecton Theory, immune system complexity, and rate of metabolism) accurately predicted the scaling of immune cell concentrations. We also evaluated the predictive power of body mass for these leukocyte concentrations compared to sociality, diet, life history,...

Data from: Palaeobiogeography and evolutionary patterns of the larger foraminifer Borelis de Montfort (Borelidae)

Davide Bassi, Juan Carlos Braga, Giovanni Di Domenico, Johannes Pignatti, Sigal Abramovich, Pamela Hallock, Janine Koenen, Zoltan Kovacs, Martin R. Langer, Giulio Pavia & Yasufumi Iryu
The palaeobiogeography of the alveolinoid Borelis species reveals the evolutionary patterns leading to the two extant representatives, which occur in shallow-water tropical carbonate, coral reef-related settings. Type material and new material of fossil Borelis species, along with Recent specimens were studied to assess their taxonomic status, species circumscriptions (based on proloculus size, occurrence of Y-shaped septula, and the index of elongation), palaeobiogeography and evolutionary dynamics. The species dealt with here are known from exclusively fossil...

Data from: DNA methylation predicts immune gene expression in introduced house sparrows (Passer domesticus)

Holly J. Kilvitis, Aaron W. Schrey, Alexandria K. Ragsdale, Alejandro Berrio, Steve M. Phelps & Lynn B. Martin
Populations undergoing range expansions are often faced with novel selective pressures, and to cope with such challenges, populations must either adapt quickly or exhibit phenotypic plasticity. This latter option allows for rapid phenotypic adjustments and persistence in novel environments, and thus could be advantageous at range‐edges. Our previous research on house sparrows in Kenya—a site of ongoing range expansion— and a growing literature suggests that invasion success is facilitated by epigenetic regulation of gene expression....
