    Overall good video, except:
    LPS is located in gram-negative bacterias and not in gram-positive.
    LTA is located in gram-positive bacterias and not in gram-negative.

    LPS is in Gram (-ve) not Gram (+ve), and LTA is in Gram (+ve) not Gram (-ve). This should be fixed by now, this could affect someone's grade. I don't mean this in a rude way by the way, I just mean PLEASE fix this so that it doesn't confuse anyone and result in them getting a lower mark.

    In case any one trying to remember thier individual function ,
    TLR 2 gram +ve bacteria LTA(two lines in plus sign)
    TLR 4 opposite =gram negative bacteria LPS
    remember TLR 3 and 7 together: 3 for double stranded viral RNA, 7 single stranded viral RNA
    TLR5 - Five for Flagellin
    TLR 9-nine for nucleic acid =DNA

  • @ivany.ramirez9924

    Armando, Karin Kolbe is right, peptidoglycan cell wall is huge for Gram positive bacteria and is the outermost "layer" of said bacteria. LPS is only on gram negative bacteria as far as I understand it. So you are right as far as what the TLR recognizes, but I think you got the "+" and "-" signs mixed up. Thanks for all the videos!

    Your Präsentations are very helpful but there is sometimes minor error. Example you exchanged the peptidoglaycan of gram +ve and gram -ve bacteria's. Lipopolysaccharide (LPS), which also called endotoxin, is found exclusively in Gram-negative bacteria, while lipoteichoic acid (LTA) is specific to Gram-positive bacteria.
