마이코박테리움 (Mycobacterium) 속에는 결핵, 우형결핵, 나병과 같이 사람과 동물에 심각한 질병을 일으키는 균 종 (species)뿐 아니라, 기회 감염균으로 일컬어지는 균 종, 그리고 자연환경에서 볼 수 있는 사물 기생의 균 종 (saprophytic species) 등 현재까지 약 72 종(species)이 알려져 있으며, 그 중 인체 질환과 관련된 것이 25종에 이르는 것으로 알려져 있다. 이러한 마이코박테리움 속은 일반적으로 사용되는 염색액으로는 용이하게 염색되지 않지만 일단 염색되면 알코올이나 염산 등으로 처리시에도 용이하게 탈색되지 않기 때문에 항산균이라고도 불린다.Mycobacterium includes not only species that cause serious diseases in humans and animals, such as tuberculosis, tuberculosis bovine tuberculosis, and leprosy, but also fungal species called opportunistic bacteria, and parasitic objects found in the natural environment. About 72 species such as saprophytic species are known so far, of which 25 are known to be related to human diseases. These Mycobacterium genus are not easily dyed with commonly used dyeing solutions, but once dyed, they are also called acid-fighting bacteria because they are not easily decolorized even when treated with alcohol or hydrochloric acid.

MAC는 주로 M. 아비움(M. avium)과 M. 인트라셀룰라(M. intracellulare)를 포함하고, 마이코박테리움 압세수스(Mycobacterium abscessus; MAB)는 주로 M. 압세수스 아종인 압세수스(M. abscessus subspecies abscessus)와 M. 압세수스 아종인 마실리엔시스(M. abscessus subspecies massiliense)를 포함한다. 최근 전세계적으로 비결핵 항산균에 기인한 폐 감염 보고가 증가하고 있지만, 건강한 개체군으로부터 비결핵 항산균 폐 감염 질환자를 구별하기 위한 바이오마커나, 질환에 대한 병태 생리의 연구가 부족한 실정이다.Nontuberculous mycobacteria (NTM) refers to mycobacteria other than Mycobacterium tuberculosis complex and Mycobacterium leprae. Meanwhile, among non-tuberculous mycobacteria belonging to the Mycobacterium avium complex (MAC), more than 180 strains have been officially identified as strains that commonly cause lung disease in humans. MAC mainly contains M. avium and M. intracellulare, and Mycobacterium abscessus (MAB) mainly contains M. abscessus subspecies Absesu. s (M. abscessus subspecies abscessus) and M. abscessus subspecies massiliense (M. abscessus subspecies massiliense). Recently, reports of lung infections caused by non-tuberculous mycobacteria have been increasing worldwide, but biomarkers for differentiating non-tuberculous mycobacterial lung infections from healthy populations or pathophysiology studies of diseases are lacking.

혈청에서 처리한 분석 시료 내의 극성 대사체를 분석하기 위하여 크로마토그래피-텐덤 질량분석기(HPLC-MS/MS)를 이용하여 분석을 진행하였다. 사용된 장비는 Agilent 1200 HPLC와 Sciex API4000 triple quadrupole MS를 이용하였다. 친수성 상호 작용을 위한 크로마토그래피 조건으로는 Luna PFPP(2.0 x 150 mm, 3μm, Phenomenex) 컬럼을 이용하여 20 ℃에서 용매에 따른 2가지 방법으로 기울기 용리를 이용하여 극성 대사체들을 분리하였다. 첫 번째 이동상으로는 (A) H2O (v/v) 및 (B) 아세토니트릴 (v/v)을 이용하였고, 두 번째 이동상으로는 (A) H2O (v/v, 0.1% formic acid) 및 (B) 아세토니트릴 (v/v)을 이용하였으며, 각각 조건의 기울기 용리는 총 분석 시간을 15분으로 하여 아래 표 1과 동일하게 수행하였다. 분무기 가스(Ion-Source Gas 1/2) 단위는 50/50 임의 단위(arbitrary unit)이었으며, 가스 커튼(Curtain Gas)의 단위는 25 임의 단위(arbitrary unit)이었다. 소스 온도(Source temperature)는 500 ℃이고, 이온 스프레이 부유 전압(Ion-spray Floating Voltage)은 5,5 kV(negative -4.5kV)이며, 매스 범위(Mass range)는 50 ~ 1000 m/z이었다. 시료 주입은 HTC_PAL system/CTC analytics auto-sampler를 이용하여 3 μl씩 주입하였으며, 텐덤 질량 분석기 조건 (예약 다중 반응 검지법; Scheduled Multiple Reaction Monitoring, sMRM)은 아래 표 2 및 3과 같이 수행하였다. 단, 하기 표 2 및 3에서 m/z는 질량 대 전하비(mass to charge ratio)를 의미하고, RT는 머무름 시간(Retention time)을 의미하며, CE는 충돌 에너지(Collision energy)를 의미하고, (+)는 양이온 모드를, (-)는 음이온 모드를 의미하며, sMRM 분석을 통해 얻어진 결과는 Sciex의 정량 분석 소프트웨어(Quantitative Analysis Software)를 통하여 로우 데이터(raw data)를 계산하였고, MQC data 평균값을 이용하여 상대 표준 편차(RSD<20)이하의 대사체를 산출하였다.In order to analyze the polar metabolites in the analysis sample treated with serum, the analysis was performed using chromatography-tandem mass spectrometry (HPLC-MS/MS). The equipment used was an Agilent 1200 HPLC and a Sciex API4000 triple quadrupole MS. As chromatography conditions for the hydrophilic interaction, polar metabolites were separated by gradient elution in two methods depending on the solvent at 20 °C using a Luna PFPP (2.0 x 150 mm, 3 μm, Phenomenex) column. (A) H 2 O (v/v) and (B) acetonitrile (v/v) were used as the first mobile phase, and (A) H 2 O (v/v, 0.1% formic acid) as the second mobile phase and (B) acetonitrile (v/v) were used, and the gradient elution of each condition was performed in the same manner as in Table 1 below with a total analysis time of 15 minutes. The unit of the Ion-Source Gas 1/2 was 50/50 arbitrary units, and the unit of the Curtain Gas was 25 arbitrary units. The source temperature was 500 °C, the ion-spray floating voltage was 5.5 kV (negative -4.5 kV), and the mass range was 50 ~ 1000 m/z. Samples were injected by 3 μl using HTC_PAL system/CTC analytics auto-sampler, and tandem mass spectrometry conditions (Scheduled Multiple Reaction Monitoring, sMRM) were performed as shown in Tables 2 and 3 below. However, in Tables 2 and 3, m/z means mass to charge ratio, RT means retention time, CE means collision energy, (+) means positive ion mode and (-) means negative ion mode. For the results obtained through sMRM analysis, raw data was calculated through Sciex's Quantitative Analysis Software, and MQC data average value was used to calculate metabolites with a relative standard deviation (RSD<20) or less.
