Of course, journalists in LA should not be targeted by police with rubber bullets. But let's not ignore the real issue of journalist safety

Immediately after Israel comes 2nd in Eurovision, BBC News comes on, and the first story is footage of Israel bombing Gaza and killing children

Someone please tell me how this is real life?

πŸ”¬ I expanded on this: instead using SAAP-148 as a preventative against AMR bacteria, applied in both HSEs and lung tissue cultures (PBECs). SAAP-148's activity was limited in PBECs against AMR bacteria, while active in HSEs due to the peptide being retained in cells

SAAP-148 and halicin exhibit synergistic antimicrobial activity against antimicrobial-resistant bacteria in skin but not airway epithelial culture models The escalating global threat of antimicrobial resistance (AMR) necessitates the development of novel antimicrobial agents, innovative strategies, and representative infection models to combat AMR bacterial infections. Host defence peptides (HDPs) and their derivatives have been proposed as complements to conventional antibiotics due to their antibacterial activity and modulation of the immune response.ObjectivesThis study investigated the novel use of the HDP-derived synthetic antibacterial and anti-biofilm peptide (SAAP)-148 as a pretreatment in epithelial tissue models to prevent colonization by AMR bacteria. The combined activities of SAAP-148 pretreatment with post-infection halicin to treat infections were also explored.MethodsEmploying cultured human skin equivalents (HSEs) and primary bronchial epithelial cells (PBECs) as models of tissue infection, we examined the prophylactic and therapeutic effects of SAAP-148, both singularly and in combination with the repurposed antibiotic halicin, against AMR bacteria. We additionally interrogated the response of HSE and PBEC cultures to SAAP-148 treatment via confocal microscopy and quantitative PCR of native HDPs and inflammatory cytokine genes.ResultsOur findings demonstrated that pretreatment with SAAP-148 significantly reduces colonization of HSEs and PBECs by AMR Staphylococcus aureus and Pseudomonas aeruginosa. Confocal microscopy revealed differential uptake and localization of SAAP-148 in these tissues, correlating with its distinct activity in these tissues. SAAP-148 exposure temporarily increased expression of the HDPs cathelicidin (CAMP) and Ξ²-defensin 1 (DEFB1), and the cytokine IL-8 (CXCL8), which did not correlate with the transient antibacterial activity observed. Sequential treatment with SAAP-148 prior to infection with AMR S. aureus and post-infection halicin treatment demonstrated synergistic activity in HSEs, whereas this combined activity was indifferent in PBEC cultures.ConclusionsThese results support SAAP-148 as a candidate for pre-infection prophylaxis and synergistic antibiotic therapy with halicin in skin, broadening the potential of both agents to address AMR bacterial infection.

🦠 AMR poses a global threat. SAAP-148 reduced colonization of AMR bacteria in skin models. It boosted HDPs & IL-8. Synergistic effects with halicin were seen in skin, not in bronchial cells.
