Description
  • We hypothesized that nucleic acids, free and/or complexed, filtered and/or locally released, might be entrapped in the kidneys because of the specific nucleic acid binding microbial pattern recognizing Toll-like receptors (TLRs). This hypothesis of nucleic acid binding potential was tested using paraffin sections from healthy control, SLE and transplant kidneys, which were labelled using TLR-specific rabbit or goat anti-human antibodies in immunoperoxidase staining. Normal and transplant kidneys contain some double-(TLR-3) and single-stranded RNA binding (TLR-8) receptors, but in particular double-stranded RNA binding receptor TLR-7, mostly in tubuli, whereas no DNA binding TLR-9 was found. SLE kidneys contain more TLR-3 and TLR-8 and express de novo also TLR-9, in particular in glomeruli. On the contrary, TLR-7 was relatively weak in SLE. It is concluded that kidneys have a capacity to bind nucleic acids. TLR stimulation leads to the production of tumour necrosis factor-alpha and other pro-inflammat

  • Předpokládali jsme, že nukleové kyseliny, ať už volné a/nebo v komplexech, filtrované a/nebo lokálně vzniklé, mohou být rozpoznány zachyceny specifickým toll-like receptory (TLR) rozeznávajícími mikrobiální nukleové kyseliny. Schopnost ledvinné tkáně vázat nukleové kyseliny byla ověřena na ledvinné tkáni kontrol, nemocných s lupusovou nefritidou a transplantovaných nemocných specifickými TLR protilátkami. Exprese RNA vázajících TLR-3, TLR-8 a TLR-7 byla pozorována zejména v tubulech kontrolního souboru. Dále byla zjištěna slabá pozitivita TLR-3 a TLR-7 v glomerulech a rovněž byla zachycena mírná pozitivita na viscerální části Bowmanova pouzdra u kontrol u TLR-7 a u TLR-8. Přítomnost TLR-9 nebyla vůbec detekována ve tkáni kontrolního souboru, zatímco tkáně s LN vykazovaly jeho expresi. U LN byla detekována vyšší exprese TLR-3 a TLR-8 v ledvinné tkáni, zvláště pak v distálních tubulech a Bowmanově pouzdru. Naproti tomu TLR-7 byl exprimován slaběji u lupusové nefritidy než u kontrol.
