Metabolic reprogramming and macrophage expansion define ACPA-negative rheumatoid arthritis: insights from single-cell RNA sequencing by Yafeng Jiang, Zhaolan Hu, Roujie Huang, Kaying Ho, Pengfei Wang, Jin Kang, Jin Kang

“…BackgroundAnti-citrullinated peptide antibodies (ACPA)-negative (ACPA−) rheumatoid arthritis (RA) presents significant diagnostic and therapeutic challenges due to the absence of specific biomarkers, underscoring the need to elucidate its distinctive cellular and metabolic profiles for more targeted interventions.MethodsSingle-cell RNA sequencing data from peripheral blood mononuclear cells (PBMCs) and synovial tissues of patients with ACPA− and ACPA+ RA, as well as healthy controls, were analyzed. …”

INBRX-120, a CD8α-targeted detuned IL-2 that selectively expands and activates tumoricidal effector cells for safe and durable in vivo responses by Jason Ho, Chelsie Macedo, Garrett Cyprus, Rajay Pandit, Anya Polovina, Nadja Kern, Abrahim Hussain, Sae Jeong Ahn, William Crago, Emily Rowell, Florian J Sulzmaier, John C Timmer, Brendan P Eckelman

“…Recent engineering efforts, including non-α IL-2 variants, have lowered the toxicity profile, but have yet to induce meaningful antitumor activity in a wider patient population.Methods We engineered INBRX-120, a CD8α-targeted Cisleukin™ molecule consisting of an affinity tuned IL-2 (IL2-x) connected to two high affinity CD8α-specific single domain antibodies via an effector-silenced Fc domain. To show that this large affinity differential enables directed IL-2 cis-signaling exclusively on CD8α-expressing tumoricidal effector cell populations, INBRX-120 effects on target cell expansion, activation and antitumor activity were tested in vitro. …”

Medication underuse in real-life practice: the impact of galcanezumab towards achieving very low frequency episodic migraine in a southeast Asian middle-income nation by Wanakorn Rattanawong, Prakit Anukoolwittaya, Akarin Hiransuthikul, Thanakit Pongpitakmetha, Auranee Trisataya, Sekh Thanprasertsuk, Alan Rapoport

“…Understanding the new concept of “Medication Underuse Headache” should encourage the health care provider to consider early intervention with calcitonin gene-related peptide (CGRP) monoclonal antibodies. Galcanezumab given early in the course of the disease, may prevent migraine chronification and have a robust response, moreso than when initiated in later stages of migraine. …”

Targets of influenza human T-cell response are mostly conserved in H5N1 by John Sidney, A-Reum Kim, Rory D. de Vries, Bjoern Peters, Philip S. Meade, Florian Krammer, Alba Grifoni, Alessandro Sette

“…Based on these observations, and the overall similarity of the neuraminidase (NA) N1 subtype encoded in both HPAI and seasonal H1N1 influenza virus as well as cross-reactive group 1 HA stalk-reactive antibodies, we expect that a degree of pre-existing immunity is present in the general human population that could blunt the severity of human H5N1 infections.IMPORTANCEInfluenza A viruses (IAVs) cause pandemics that can result in millions of deaths. …”

SPA14 liposomes combining saponin with fully synthetic TLR4 agonist provide adjuvanticity to hCMV vaccine candidate by Ernesto Luna, Sophie Ruiz, Marie Garinot, Cyril Chavagnac, Pankaj Agrawal, John Escobar, Laurent Revet, Marie-Jeanne Asensio, Fabienne Piras, Francis G. Fang, Donald R. Drake, Bachra Rokbi, Daniel Larocque, Jean Haensler

“…When tested as an adjuvant in vivo with human cytomegalovirus glycoprotein B (gB) and pentamer complex (PC) as test antigens, SPA14 was generally well tolerated and as active as AS01B for the induction of long-lasting CMV-neutralizing antibodies in mice and non-human primates (NHPs). Both adjuvants promoted the induction of Th-1 responses based on IgG2c production in mice and IFN-γ production in mice and NHPs, but in mice, a higher level of Th-2 cytokines (IL-5) and higher IgG1 over IgG2c secreting cells ratios were obtained with SPA14 indicating that the adjuvant profile of SPA14 could be less Th-1 biased than that of AS01B. …”
