Bioactive peptides in cancer and inflammation: Mechanisms, model systems and clinical translation

open access: yesClinical and Translational Discovery, Volume 6, Issue 5, October 2026.
Bioactive peptides (BAPs) derived from host, marine, insect, plant and synthetic sources share cationic, amphipathic structures adopting α‐helical, β‐sheet or cyclic conformations. These features underlie anti‐cancer effects, including membrane disruption, apoptosis and cell‐cycle arrest, anti‐metastatic activity, reduced invasion and migration, and ...

Neutrophil Extracellular Traps in Atherosclerosis and Cardiovascular Disease

open access: yesMedComm, Volume 7, Issue 10, October 2026.
NETs as integrated effectors in the atherosclerotic cardiovascular disease continuum. Activated neutrophils release NETs that promote endothelial injury, thrombo‐inflammation, and plaque destabilization throughout atherosclerotic disease progression. Created with BioRender.com.

Global Proteomic Analysis of Sperm and Seminal Plasma From Tropically‐Adapted Rams With Contrasting Parameters of Frozen‐Thawed Semen

open access: yesMolecular Reproduction and Development, Volume 93, Issue 10, October 2026.
ABSTRACT The aim of this study was to characterize the proteome of sperm and seminal plasma (SP) from rams with high semen freezability (HF) and low semen freezability (LF). Eleven ejaculates were collected from 12 rams, at 3‐day intervals, and cryopreserved (132 semen samples).

Mast Cells in Host Defense Against Cutaneous Staphylococcus aureus Infection

open access: yesImmunology &Cell Biology, Volume 104, Issue 9, Page 867-880, October 2026.
Impact of S. aureus epicutaneous sensitization models on mast cell function in vivo. D. farinae and Staphylococcal enterotoxin B (SEB) activate Trpv1+ Tac1+ nociceptors to trigger the release of substance P (SP), which promotes mast cell degranulation through Mrgprb2. S.

The human cathelicidin LL-37 preferentially promotes apoptosis of infected airway epithelium [PDF]

open access: yes, 2010
Cationic host defense peptides are key, evolutionarily conserved components of the innate immune system. The human cathelicidin LL-37 is an important cationic host defense peptide up-regulated in infection and inflammation, specifically in the human lung,

The human cathelicidin antimicrobial peptide LL-37 and mimics are potential anticancer drugs

open access: yesFrontiers in Oncology, 2015
Antimicrobial peptides (AMPs) play a critical role in innate host defense against microbial pathogens in many organisms. The human cathelicidin LL-37 has a net positive charge and is amphiphilic, and can eliminate pathogenic microbes directly via ...

Mechanism‐Informed Machine Learning Enables Discovery of Oncolytic Peptides for Cancer Immunotherapy

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
MISPOP integrates ensemble learning with membrane‐active physicochemical priors to identify Dermaseptin‐S9, a natural oncolytic peptide that disrupts tumor membranes, triggers immunogenic cell death, and shows strong antitumor activity. The study illustrates a mechanism‐informed route from peptide sequence data to cancer immunotherapy leads.

Expression and function of cathelicidin hCAP18/LL-37 in chronic lymphocytic leukemia

open access: yesHaematologica, 2020
Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of clonal Bcellsin peripheral blood and lymphoid tissues 1. Circulating CLL cells are non-dividing Blymphocytes, but a significant fraction of the clone proliferates in lymphoid tissues wherethey receive a plethora of signals from the microenvironment that promote their survivaland

Role of ClpX and MsrA/B in the Oxidative and Cell Wall Stress Response in Bacillus anthracis Sterne

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Methionine sulfoxide reductase (msrA/B) is an oxidative response enzyme that reduces oxidized methionine residues to maintain protein function. Surprisingly, loss of MsrA/B does not increase sensitivity to hydrogen peroxide or paraquat‐induced oxidative stress in Bacillus anthracis Sterne.

Pathogenesis of Tuberculosis: Interplay Between Host Antituberculosis Immunity and Immune Evasion Strategies of Mycobacterium Tuberculosis

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Mycobacterium tuberculosis–host interactions and infection outcomes. Following initial infection, alveolar macrophages phagocytose the pathogen, prompting the recruitment of innate immune cells including neutrophils, NK cells, and interstitial macrophages.
