Cov lymphocytes yog dab tsi? Cia peb kawm txog peb lub cev lub zog tiv thaiv!

Koj puas tau saib qhov kev kuaj ntshav thiab pom tias muaj pes tsawg cov qe ntshav dawb (WBCs) nyob hauv? Ntxiv rau cov qe ntshav liab uas muab xim liab rau peb cov ntshav, peb kuj muaj cov qe ntshav dawb uas tseem ceeb heev rau peb lub cev. Cov qe ntshav dawb no yog peb cov tub rog uas tiv thaiv peb lub cev ntawm cov kab mob thiab cov kab mob. Cov tub rog tshwj xeeb thiab txawj ntse tshaj plaws hauv cov tub rog ntawd yog cov lymphocytes uas peb tab tom tham txog niaj hnub no.

Lub luag haujlwm ntawm lymphocytes yog dab tsi?

Hais yooj yim xwb, cov lymphocytes yog lub hauv paus ntawm peb lub cev tiv thaiv kab mob. Lawv tsim txog li 20% txog 40% ntawm peb cov qe ntshav dawb tag nrho. Ib yam li ib pab tub rog tiv thaiv ib lub teb chaws, cov qe ntshav no tawm tsam cov yeeb ncuab uas nkag mus rau hauv peb lub cev. Cov yeeb ncuab no tuaj yeem yog:

• Cov kab mob
• Cov kab mob
• Cov hlwb qog noj ntshav

Cov lymphocytes tam sim ntawd pib ua haujlwm los tawm tsam txhua tus neeg txawv teb chaws (peb hu cov antigens no). Thiab cov lymphocytes no muaj peev xwm zoo kawg nkaus. Ntawd yog kev nco qab . Xav txog, tom qab koj muaj mob qhua pias thaum koj tseem yog menyuam yaus, koj yuav tsis mob qhua pias dua. Qhov laj thawj rau qhov no yog tias thaum tus kab mob qhua pias nkag mus rau hauv peb lub cev, cov lymphocytes no paub nws thiab tawm tsam nws. Tom qab ntawd, lawv khaws cia lub cim xeeb ntawm tus kab mob ntawd hauv daim ntawv ntawm "cov hlwb nco qab". Yog tias tus kab mob nkag mus rau hauv peb lub cev dua, cov hlwb nco qab no paub nws sai li sai tau thaum lawv pom nws thiab rhuav tshem nws sai sai. Ua ntej peb txawm mob! Cov tshuaj tiv thaiv peb siv los tiv thaiv peb tus kheej los ntawm cov kab mob ua haujlwm ntawm lub hauv paus ntsiab lus no. Lymphocytes raug tsim tawm hauv peb cov pob txha pob txha. Los ntawm qhov ntawd, lawv raug ntxiv rau cov ntshav thiab kis thoob plaws peb lub cev lymphatic. Lub cev lymphatic suav nrog cov kabmob zoo li peb cov qog ntshav thiab cov qog thymus.

Cov hom lymphocytes tseem ceeb yog dab tsi?

Cov lymphocytes muaj ob hom loj: B cell thiab T cell. Ua ke, ob hom no ua rau peb lub cev tiv thaiv kab mob muaj zog.

Cov Qog B Ua Haujlwm Li Cas

Thaum cov qe ntshav B paub txog ib qho antigen, lawv teb ob txoj kev. 1. Kev Tiv Thaiv Kab Mob Thawj Zaug: Thawj zaug uas cov antigen nkag mus rau hauv lub cev, cov qe ntshav B paub txog nws, thiab qee cov qe ntshav B dhau los ua cov qe ntshav nco. Lwm cov dhau los ua cov qe ntshav plasma thiab pib ua cov tshuaj tiv thaiv kab mob uas tshwj xeeb rau cov antigen ntawd. Qhov no tuaj yeem siv sijhawm ob peb hnub. 2. Kev Tiv Thaiv Kab Mob Thib Ob: Yog tias pom tib qho antigen dua, cov qe ntshav nco yuav paub nws sai sai, ua cov qe ntshav plasma sai sai, thiab tsim cov tshuaj tiv thaiv kab mob tsim nyog sai sai.

Hom T Cells

Cov qe ntshav T muaj teeb meem ua haujlwm ib leeg xwb, lawv xav tau kev pab los ntawm lwm cov qe ntshav tiv thaiv kab mob. Tom qab tau txais kev pab, cov qe ntshav T faib ua ntau hom thiab ua haujlwm.

• Cov qe ntshav T Cytotoxic/Killer: Cov no mus ncaj qha rau cov qe ntshav uas muaj kab mob lossis cov qe ntshav qog thiab rhuav tshem lawv.
• Cov qe ntshav T pab: Raws li lub npe qhia, cov no pab lwm cov qe ntshav tiv thaiv kab mob. Lawv ua tej yam xws li pab cov qe ntshav B tsim cov tshuaj tiv thaiv thiab ua kom cov qe ntshav T tua tau.
• Cov qe ntshav T uas tswj hwm : Cov no tiv thaiv lub cev tiv thaiv kab mob kom tsis txhob ua haujlwm ntau dhau thiab ua rau peb lub cev puas tsuaj. Qhov ntawd yog, lawv tswj lub cev.

Yuav ua li cas los xyuas cov theem ntawm lymphocytes?

Muaj ntau yam kev kuaj ntshav uas ua tau los txiav txim siab koj cov lymphocyte suav.

• Kev Ntsuas Ntshav Tag Nrho (CBC): Qhov no yog tib daim ntawv qhia FBC ( Kev Ntsuas Ntshav Tag Nrho ) uas peb feem ntau ua. Nws ntsuas qhov ntau ntawm txhua yam hauv cov ntshav, suav nrog cov qe ntshav liab, cov qe ntshav dawb, thiab cov qe ntshav dawb.
• Kev ntsuas ntws ntawm cov kua dej:Qhov no yog ib qho kev xeem nyuaj dua li CBC. Nws suav tau ntau hom lymphocytes, xws li B cell thiab T cell, thiab txiav txim siab seb lawv muaj pes tsawg.
• Kev kuaj mob B thiab T cell: Koj tus kws kho mob yuav kom koj kuaj qhov kev kuaj no yog tias koj xav tias koj muaj teeb meem ntawm lub cev tiv thaiv kab mob. Nws kuj tseem tuaj yeem pab nrhiav tau mob qog noj ntshav lossis mob qog nqaij hlav.

Cia peb kawm txog qhov nce thiab txo qis ntawm cov lymphocytes.

Cov lymphocytes ib txwm muaj yuav txawv me ntsis nyob ntawm hnub nyoog, poj niam txiv neej, qhov siab, thiab kev ua neej. Yog li ntawd, nrog koj tus kws kho mob tham kom tau txais kev nyeem ntawv raug ntawm koj daim ntawv qhia.

• Tus nqi ib txwm rau cov neeg laus: Nruab nrab ntawm 1,000 thiab 4,800 lymphocytes ib microliter ntawm cov ntshav.
• Tus nqi ib txwm muaj rau cov menyuam yaus: Nruab nrab ntawm 3,000 thiab 9,500 lymphocytes ib microliter ntawm cov ntshav.

Kev nce lossis txo qis ntawm cov lymphocytes siab dua li qub tuaj yeem yog cov tsos mob ntawm qee yam mob.

Cov tsos mob ntawm cov kab mob lymphocyte tsis zoo yog dab tsi?

Feem ntau, tej zaum yuav tsis muaj tsos mob li, tab sis qee tus neeg yuav muaj cov tsos mob xws li:

• Kev o ntawm cov pob qij txha (kev o ntawm cov pob qij txha)
• Kev hws hmo ntuj
• Ua npaws
• Mob plab
• Kev ntshaw noj mov
• Ua pa nyuaj

Yog tias koj muaj cov tsos mob zoo li no, lossis yog tias koj muaj kev tsis ntseeg txog cov nqi hauv koj daim ntawv qhia ntshav, qhov zoo tshaj plaws ua yog mus ntsib kws kho mob sai li sai tau thiab nrhiav kev pab tswv yim.
