- Example 10 KRS Immune cell migration-related disease of -N term specific binding antibody in vivo Efficacy check in model_ in vivo Pulmonary arterial hypertension model
- the KRS N-term specific antibody of the present invention (typically N3 antibody) will show a therapeutic effect on immune cell migration-related diseases, which was further proved through the examples described below.
- PAH Pulmonary arterial hypertension
- MCT monocrotaline
- N3 IgG antibody 1mpk N3 IgG antibody 10mpk
- sildenafil positive control 25 mpk administered for 3 weeks
- All antibodies were injected iv twice a week and sildenafil was orally administered daily.
- rats were anesthetized with isoflurane, and blood flow and pressure were measured using an animal ultra-precision pneumatic measurement system (MPVS Cardiovascular Pressure and Volume system, Model: MPVS Ultra, Manufacturer: Millar Instruments).
- RVESP Right ventricular systolic pressure
- diastolic pressure left ventricular systolic and diastolic pressure are dedicated catheter (Mikro-Tip) rat pressure catheter, manufacturer: Millar Instruments).
- Cardiac output is perivascular blood flow probe (Transonic) Flowprobes, manufactured by: Millar Instruments), and the experimental technique for this was performed in the same manner as described in the following documents: Pacher P, Nagayama T, Mukhopadhyay P, Batkai S, Kass DA. Measurement of cardiac function using pressure-volume conductance catheter technique in mice and rats. Nat Protoc 2008; 3 (9): 1422-34.
- the collected lungs were fixed in paraformaldehyde (PFA) according to a conventional procedure, and then washed with water, dehydrated, and transparently infiltrated and paraffin penetrated.
- the paraffin block of rat tissue was sliced to a thickness of 3 ⁇ m and a slide was prepared. Then, staining was performed as follows. First, after treating xylene 3 times for 5 minutes, 100% ethanol, 95% ethanol, 90% ethanol, 70% ethanol, and DW were treated for 2 minutes, followed by washing with PBS for 5 minutes. After treatment with 0.3% H 2 O 2 , the samples were washed twice with PBS for 5 minutes.
- the stained tissue was treated with Mayer's hematoxylin (Sigma) for 1 minute, and then treated twice in each order of 70% ethanol, 90% ethanol, 95% ethanol, and 100% ethanol for 2 minutes. Finally, after xylene treatment 3 times for 5 minutes, it was observed with an optical microscope.
- RVESP right ventricular end-systolic pressure
- RVVEDP right ventricular end-diastolic pressure
- LVESP left ventricular end-systolic pressure
- CO cardiac output
- Pulmonary arterial hypertension increases the right ventricular pressure due to the narrowing of the pulmonary artery, resulting in right ventricular failure.
- the compensatory mechanism is destroyed by persistent hypertension, right ventricular hypertrophy and right ventricular dilatation occur. This is led to the left ventricular pressure due to movement of the ventricular septum is led to a reduction in the expansion end volume and cardiac output of the left ventricle (yiwooseok et al., Clinical characteristics and outcome prediction in severe pulmonary hypertension factor, Korean Circulation J 2007; 37 : 265-270 ). Consequently, pulmonary arterial hypertension is primarily associated with the right ventricle, but also with the function of the left ventricle.
- RVESP is increased in PAH patients, which has also been confirmed in the PAH animal model of this experiment.
- N3 antibody KRS-N term specific binding antibody
- LVESP left ventricular systolic pressure
- the N3 antibody of the present invention shows a low tendency to have an effect on systemic artery pressure compared to Sildenafil, and this effect has a situation in which the risk of hypotension occurs when Sildenafil is administered in a clinical field.
- severe pulmonary arterial hypertension may be accompanied by low cardiac output and systemic hypotension, as systolic RV failure occurs.
- the cardiac output and systemic blood pressure are increased by the treatment of improving pulmonary arterial hypertension by the N3 antibody of the present invention, and the effect of normalizing blood pressure is expected.
- Example 11 KRS Immune cell migration-related disease of -N term specific binding antibody in vivo Efficacy check in model _ Acute lung injury model
- the acute lung injury model was constructed by injecting 2.5 mg / kg of LPS (Sigma) into the trachea in a 7-week-old male C57BL / 6 mouse (Dooyeol Bio).
- the BALF obtained by washing the lungs with PBS was collected and centrifuged at 4 ° C for 10 minutes at 800 x g to collect pellets. After floating the cells, red blood cells were removed using RBC lysis buffer (eBioscience cat.no.00-4333-57). Thereafter, the reaction was stopped with PBS, washed twice, and suspended in 400 ⁇ l PBS to measure the cell number with a hemocytometer and neutrophil number through Hema3 staining.
- the lung tissue was collected and crushed by rotating it at 37 ° C for 45 minutes using gentleMACS Octo Dissociator (MACS Miltenyi Biotec, Order no.130-095-937) equipment. After filtering using a cell strainer (40 ⁇ m), centrifugation was performed at 1500 rpm for 5 minutes at room temperature. Pellet was collected and red blood cells were removed using RBC lysis buffer (eBioscience cat.no.00-4333-57). The cells were collected, suspended in FACS buffer (PBS containing 1% NaN3 and 3% FBS), and then put 50 ⁇ l in a tube, mixed well with the same amount of antibody mxiture, and stained by blocking light for 1 hour at 4 ° C.
- FACS buffer PBS containing 1% NaN3 and 3% FBS
- FITC Rat Anti-CD11b (BD Pharmingen) and PE Rat Anti-Mouse F4 / 80 (BD Pharmingen) antibodies were used. After washing twice at 400 x g for 5 minutes using FACS buffer, it was analyzed with a Navios Flow Cytometer (Beckman) instrument.
- the lung tissue was paraffin-embedded in a conventional manner, and then cut off. After that, the tissue slide from which paraffin was removed using xylene was washed with DW, and then treated with Bouin Fluid at 56-60 ° C for 1 hour. It was dyed for 10 minutes with Weigert's iron hematoxylin solution, then washed, and then stained with Biebrich scarlet-acid fuchsin solution for 10-15 minutes and then washed. Phosphomolybdic-phosphotungstic acid solution was treated for 10-15 minutes, transferred to an aniline blue solution, and stained for 5-10 minutes. After washing, treated with 1% acetic acid solution for 2-5 minutes. After washing and dehydration, xylene treatment was performed to mount.
- Interstitial macrophage is a CD11b + / F4 / 80 + cell that is not resident in the lung and migrates to the lung in certain situations (migrating macrophages).
- LPS treatment increased the infiltration of IM into the lungs, but N3 antibody treatment decreased concentration-dependent migration of IM into the lungs.
- N3 antibody treatment decreased concentration-dependent migration of IM into the lungs.
- the migration and infiltration of immune cells such as macrophages / monocytes into the lung tissue is an important pathological phenomenon in tissue fibrotic diseases.
- tissue fibrotic diseases As a result of observing the lung tissue by Masson's trichrome staining for the acute lung injury model (FIG. 17), it was confirmed that fibrosis in the lung tissue progressed significantly, and for this, an N3 antibody (an antibody that specifically binds to KRS N-term) The treatment confirmed that this fibrosis was suppressed.
- Example 12 Analysis of immune cell migration of mutant antibodies without ADCC / CDC function
- a transwell chamber with a polycarbonate membrane (5.0 ⁇ m pore size, Costar).
- LN421 was added to a lower chamber at a concentration of 2.5 ⁇ g / ml.

- the upper chamber was placed in 33% acetic acid (Merck) and stirred for 10 minutes.
- the acetic acid solution in which the crystal violet was dissolved was transferred to a 96-well plate and absorbance was measured at 590 nm in a microplate reader (Tecan).
- N3-8, N3-8-1, N3-8-1 mutant LALA, N3-8-1 mutant LALATA, N3-8-1 mutant LALAPG, N3-8-1 mutant LALAPGTA It was shown that the antibodies inhibited cell migration by LN421 to a level similar to that of the control (Control, C), which did not process anything.
- N3-8, N3-8-1, N3-8-1 mutant LALA, N3-8-1 mutant LALATA, N3-8-1 mutant LALAPG, and N3-8-1 mutant LALAPGTA antibodies were each 10 nM in the chamber. And cultured for 7 hours. The non-migrating cells present on the membrane were removed with a cotton swab, washed twice with PBS, and treated with 70% MeOH (in PBS) for 30 minutes. Again washed twice with PBS, stained with crystal violet (SIgma), and dried. Then, the upper chamber was stirred in 33% acetic acid (Merck) and stirred. The acetic acid solution in which the crystal violet was dissolved was transferred to a 96-well plate and absorbance was measured at 590 nm in a microplate reader (Tecan).
