Pehea e hoʻouka ai nā pathogens i ka ʻōnaehana pale
He mea kupanaha ka ʻōnaehana pale kino kanaka o ka ʻenekinia olaola, e hana ana ma ke ʻano he ʻano pale o ke kino e ʻike, hakakā, a hoʻopau i nā mea komo hewa mai nā ʻāina ʻē. Eia nō naʻe, ua hoʻomohala nā pathogens—nā meaola e hoʻoulu ai i ka maʻi—i nā ʻano hana akamai he nui e uhaki i kēia mau pale. ʻO ka hoʻomaopopo ʻana i ke ʻano o ka hoʻouka ʻana o kēia mau microorganisms, ʻo ia hoʻi nā bacteria, nā virus, nā fungi, a me nā parasites, i ka ʻōnaehana pale he mea nui ia no ka hoʻomohala ʻana i nā lāʻau lapaʻau a me nā lāʻau pale. Ke nānā nei kēia ʻatikala i nā ʻano hana like ʻole a nā pathogens e hoʻohana ai e hoʻohaʻahaʻa i kā mākou pale ʻana.
ʻO ka Laina Pale Mua o ka ʻŌnaehana Palekana
Ma mua o ke komo ʻana i loko o nā hana a nā pathogens, he mea nui e hoʻomaopopo i ke ʻano pale papa o ka ʻōnaehana pale. Hana ka ʻōnaehana pale kūlohelohe ma ke ʻano he laina pale mua a hoʻokomo pū i nā pale kino e like me ka ʻili a me nā membrane mucous, a me nā mea pale cellular e like me macrophages, neutrophils, a me nā cell pepehi kanaka kūlohelohe. Ke uhaki ʻia ka ʻōnaehana pale kūlohelohe, lawe ka ʻōnaehana pale adaptive, i hōʻailona ʻia e ka hana i kuhikuhi ʻia o nā cell T a me nā cell B, ka mea e ʻike i nā antigens kikoʻī a hana i ka hoʻomanaʻo immunological.
ʻAno Malu: Nā Hana Pale ʻAna
ʻO kekahi o nā ʻano hana mua e hoʻouka ai nā pathogens i ka ʻōnaehana pale ma o ka pale ʻana. Ma ka hoʻololi ʻana i nā molekala ʻili a i ʻole ka peʻe ʻana i loko o nā cell host, hiki i kēia mau mea hoʻouka kaua ke pakele ma mua o ka nānā ʻana o ka pale. Hoʻohana pono nā virus e like me HIV a me Epstein-Barr i kēia hoʻolālā.
ʻOkoʻa Antigenic
Hiki i nā pathogens he nui ke hoʻololi i nā protein ma ko lākou mau ʻili, kahi hoʻololi i ʻike ʻia ʻo ka antigenic variation. No ka laʻana, he nui nā ʻano o ka maʻi influenza me nā protein ʻili like ʻole (hemagglutinin a me neuraminidase), e paʻakikī ai i ka ʻōnaehana pale ke ʻike a hoʻomanaʻo iā lākou.
Ka Hūnā ʻana i loko o ke kelepona
Hele kekahi mau pathogens i kahi ʻanuʻu hou aʻe, e peʻe ana i loko o nā pūnaewele hoʻokipa. ʻO Mycobacterium tuberculosis, no ka laʻana, hiki ke noho i loko o nā macrophages, nā hunaola koko keʻokeʻo i manaʻo ʻia e luku iā lākou. Ma ka noho ʻana i loko o kēia mau pūnaewele, pale aku ka bacteria i ka ʻike ʻana a me ka luku ʻia e nā pūnaewele pale ʻē aʻe.
Kāmeuflage Palekana: Hoʻokumu ʻana o Biofilm
ʻO nā Biofilms he mau kaiāulu bacteria i hoʻonohonoho ʻia i loko o kahi matrix polymeric i hana ponoʻī ʻia e pili ana i nā ʻili a kūpaʻa loa i nā pane pale a me nā antibiotics. ʻO ka unuhi ʻana i nā bacteria mai kēia mau biofilms a me ka hana ʻana me lākou pākahi e lilo i hana herculean no ka ʻōnaehana pale. He mea hana biofilm kaulana ʻo Pseudomonas aeruginosa, i pili pinepine ʻia i nā maʻi maʻi mau i nā poʻe me nā ʻōnaehana pale i hoʻopilikia ʻia, e like me ka poʻe me ka cystic fibrosis.
Ka Hoʻopunipuni ʻana i ka ʻōnaehana pale
Ma waho aʻe o ka pale ʻana, ua ulu aʻe kekahi mau pathogens e hoʻopunipuni pololei i ka ʻōnaehana pale i ko lākou pono. Hiki iā lākou ke hoʻokahuli i nā pūnaewele pale, hoʻopilikia i nā ala hōʻailona, a i ʻole hana i nā molekala e kāohi i ka hana pale.
ʻO ka hoʻololi kino
Hiki i kekahi mau virus, e like me Cytomegalovirus (CMV), ke hoʻololi i ka hōʻailona cytokine, kahi ʻano kamaʻilio ma waena o nā cell i loko o ka ʻōnaehana pale. Ma ka hoʻopilikia ʻana me nā cytokines e like me interleukin-10 (IL-10), hiki i kēia mau pathogens ke kāohi i nā pane pale, e hānai ana i kahi kaiapuni kahi e hiki ai iā lākou ke ulu.
Ka Hoʻopilikia ʻana o ke Kelepona Hōʻike Antigen (APC)
Hiki i nā pathogens e like me Herpes Simplex Virus (HSV) ke kāohi i ka hana o nā cell antigen-presenting (APCs), me nā cell dendritic a me nā macrophages. Ma ka hoʻopau ʻana i kēia mau cell, pale ka pathogen i ka hoʻāla pono ʻana o nā cell T, a laila hoʻonāwaliwali i ka pane pale adaptive.
Ka nui o ka ʻōnaehana pale maʻi
ʻO kekahi hana a nā pathogens e hoʻohana ai, ʻo ia ke hoʻouka i ka ʻōnaehana pale ma o ka hoʻonui wikiwiki ʻana a i ʻole ka hana ʻana i nā nui o nā toxins.
Hoʻonui wikiwiki
ʻO nā bacteria e like me Vibrio cholerae, ke kumu o ka cholera, e ulu nui ana, e hana ana i ka nui o nā bacteria e hoʻokuʻu i ka toxin cholera. Ke hakakā nei ka ʻōnaehana pale e mālama i kēia hoʻonui wikiwiki ʻana, e alakaʻi ana i nā hōʻailona maʻi koʻikoʻi, me ka maʻi diarrhea a me ka dehydration.
Nā Superantigens
ʻO kekahi mau pathogens, ʻoiai kekahi mau ʻano Staphylococcus aureus a me Streptococcus pyogenes, hana i nā superantigens. ʻO kēia nā protein microbial e hoʻonui i ka ʻōnaehana pale, e hopena ana i kahi pane pale nui a ʻaʻole kikoʻī. Hiki i kēia pane nui ke hōʻeha nui i nā ʻiʻo, kahi i hoʻohana ʻia e ka pathogen e hoʻoikaika i kona ola ponoʻī a me ka hoʻonui ʻana.
Hoʻohālikelike ʻōnaehana pale
ʻO ka hoʻohālike molekala kekahi hana ʻē aʻe i hoʻohana ʻia e nā pathogens e pale aku i ka ʻike ʻana o ka pale ʻana. Ma ka hoʻohālike ʻana i nā molekala kikowaena, hiki i kēia mau mea hoʻouka kaua ke hoʻopunipuni i ka ʻōnaehana pale e manaʻo he ʻāpana lākou o ke kino.
Hoʻohālikelike Molekala
ʻO kahi laʻana koʻikoʻi o kēia ʻo ia ka bacteria Streptococcus pyogenes, ka mea e hoʻoulu ai i ka strep throat a me nā maʻi ʻē aʻe. Ua like loa nā ʻāpana o ka paia cell bacteria me nā ʻiʻo kanaka, e alakaʻi ana i kahi pane pale kino e hiki ke hoʻouka i nā cell ponoʻī o ke kino, e hopena ana i nā kūlana autoimmune e like me ka rheumatic fever.
Hoʻololi i ke kaiapuni kikowaena
ʻAʻole wale ka peʻe ʻana a ka hoʻopunipuni ʻana o nā pathogens; hoʻololi ikaika lākou i ke kaiapuni kikowaena e hōʻoia i ko lākou ola.
ʻO ka palakiko Phenotypic
ʻO Candida albicans, kahi pathogen fungal, hiki ke hoʻololi i kona ʻano ma muli o ke kaiapuni. Hiki iā ia ke hoʻololi mai kahi hū i kahi ʻano hyphal, e ʻae ana iā ia e komo i nā ʻiʻo a pale i ka ʻōnaehana pale. ʻO kēia ʻano o ka plasticity phenotypic e kōkua i ka pathogen e ola a hoʻolaha i loko o nā niches host like ʻole.
Hopena: Ka Heihei Kaua
Ua like ka pilina ma waena o nā pathogens a me ka ʻōnaehana pale me kahi heihei kaua, me kēlā me kēia ʻaoʻao e hoʻomohala mau nei i nā hoʻolālā hou a me nā hana kūʻē. I ka hoʻomohala mau ʻana o nā pathogens i nā ʻano hana hou e hoʻouka a pale aku i ka ʻōnaehana pale, hoʻoikaika nā kānaka ʻepekema a me nā mea noiʻi lapaʻau e mālama i ka wikiwiki ma o ka hoʻomohala ʻana i nā lāʻau lapaʻau hou, nā lāʻau pale, a me nā mea hana diagnostic.
ʻO ka hoʻomaopopo ʻana i nā ʻano paʻakikī e hoʻohana ai nā pathogens i ka ʻōnaehana pale ʻaʻole wale ia e hāʻawi i ka ʻike i nā ʻano hana maʻi akā e hoʻomālamalama pū i nā ala kūpono no ke komo ʻana o ka therapeutic. ʻO ka hoʻopaʻa ʻana i kēia mau hana pale a me ka hoʻopunipuni paʻakikī e hāʻawi i kahi ala hoʻohiki no ka hanauna e hiki mai ana o nā holomua lapaʻau, e manaʻo ana e hoʻohuli i ke kaulike ma ka ʻōnaehana pale a kūʻē i nā pathogens e hoʻoweliweli nei i ko mākou olakino.
He mau loa ke kaua ma waena o nā pathogens a me ka ʻōnaehana pale, akā me ka hoʻomau ʻana o ka noiʻi a me ka hana hou, ʻoi aku ka maikaʻi o ko mākou manawa e lanakila ai.
