The laminar organization of the Drosophila ellipsoid body is semaphorin-dependent and prevents the formation of ectopic synaptic connections

open access: yeseLife, 2017
The ellipsoid body (EB) in the Drosophila brain is a central complex (CX) substructure that harbors circumferentially laminated ring (R) neuron axons and mediates multifaceted sensory integration and motor coordination functions.

Low‐Dose H2O2 Priming Improves Performance Under Simulated Marine Heatwave Conditions in a Coastal Bivalve

open access: yesGlobal Challenges, Volume 10, Issue 6, June 2026.
Low‐dose hydrogen peroxide priming shapes Manila clam responses to simulated marine heatwaves, which showed faster burrowing behavior, limited transcriptional disruption, and reduced opportunistic microbiota. A long‐term field trial confirms no detectable adverse effects, supporting redox‐based chemical priming as a feasible resilience strategy in ...

An Open‐Label Phase 1b Study of the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of ANX005 in Patients with Huntington's Disease

open access: yesMovement Disorders, Volume 41, Issue 6, Page 1492-1501, June 2026.
Complement activation is implicated in Huntington's disease; ANX005 is a potent inhibitor of component C1q. ANX005 exhibited a generally manageable safety profile with rapid reduction in C1q in the cerebrospinal fluid. Functional ability on composite Unified Huntington's Disease Rating Scale and total functional capacity was maintained, with potential ...

Semaphorin 3F and Netrin-1: The Novel Function as a Regulator of Tumor Microenvironment

open access: yesFrontiers in Physiology, 2018
Axon guidance molecules play an important role in regulating proper neuronal networking during neuronal development. They also have non-neuronal properties, which include angiogenesis, inflammation, and tumor development. Semaphorin 3F (SEMA3F), a member

Semaphorin Receptor Function in Hedgehog Signal Transduction [PDF]

open access: yes, 2018
Hedgehog signaling is a conserved cell-cell communication pathway that plays essential and diverse roles during embryonic development and adult tissue homeostasis. Many cell surface-associated molecules critically regulate the Hedgehog signaling pathway,

Semaphorin-7A blocks α-SMA and periostin production in HLF.

open access: yes, 2017
HLF derived from non-fibrotic lungs were treated with the indicated siRNAs for 24 h. HLF were subsequently starved in BSA for 24 h before either adding TGF-ß (1 ng/ml) or left in BSA for 20 h.

Immunohistochemical distribution of Plexin A4 in the adult rat central nervous system

open access: yesFrontiers in Neuroanatomy, 2010
PlexinA4 is the latest member to be identified of the plexin A subfamily, critical transducers of class 3 semaphorin signaling as co-receptors to neuropilins 1 and 2.

From HBV to MASLD Cirrhosis: Mechanistic Insights and Therapeutic Strategies

open access: yesPortal Hypertension &Cirrhosis, Volume 5, Issue 2, Page 170-188, June 2026.
This review examines the epidemiological shift from hepatitis B virus (HBV) to metabolic dysfunction‐associated steatotic liver disease (MASLD) as the leading cause of cirrhosis globally. It highlights the distinct pathogenic mechanisms between HBV and MASLD cirrhosis and discusses evolving diagnostic tools and therapeutic strategies tailored to the ...
