CNS-Native Myeloid Cells Drive Immune Suppression in the Brain Metastatic Niche through Cxcl10 [R10_PD-L1+VISTA treatment]

ABSTRACT: We performed CITE-seq (10x Genomics-based) to profile and compare the transcriptomes and cell surface expression of immune epitopes in the brains of anti-VISTA+anti-PD-L1 treated (Dual TX) and control, non-treated mice. We sequenced a total of eight samples (4 control, 4 dual TX). We created an antibody pool consisting of 35 different antibodies and stained each sample individually with this antibody pool. Then, we stained each sample with it's own unique hashing antibody so that we could subsequently pool the samples for loading onto the 10x Chromium and later prepare one library consisting of all sight samples and finally separate each sample in silico by it's unique hashing antibody. The samples are as follows: (1) HTO1: Control/Non-treated (2) HTO2: Control/Non-treated ; (3) HTO3: Control/Non-treated ; (4) Control/Non-treated ; (5) HTO5: Dual TX; (6) Dual TX; (7) HTO7: Dual TX; (8) HTO8: Dual TX. The following sample comparisons were made: HTO1 - HTO4 were compared to HTO5 - HTO8.

Chemotherapy-mediated changes in the immune cell landscape of murine triple negative breast cancer.

Project description:We performed CITE-seq (10x Genomics-based) to profile and compare the transcriptomes and cell surface expression of immune epitopes in the primary breast tumors of transgenic mice (C3-1-TAg) with or without MCT chemotherapy. We sequenced a total of six different tumor samples. We created an antibody pool consisting of 35 different antibodies and stained each sample individually with this antibody pool. Then, we stained each sample with it's own unique hashing antibody so that we could subsequently pool the samples for loading onto the 10x Chromium and later prepare one library consisting of all sight samples and finally separate each sample in silico by it's unique hashing antibody. The samples are as follows: (1) HTO1: tumor of PBS treated C3-1-TAg mouse; (2) HTO2: tumor of PBS treated C3-1-TAg mouse; (3) HTO3: tumor of PBS treated C3-1-TAg mouse; (4) HTO4: tumor of MCT treated C3-1-TAg mouse; (5) HTO5: tumor of MCT treated C3-1-TAg mouse; (6) HTO6: tumor of MCT treated C3-1-TAg mouse. The following sample comparisons were made: HTO1, HTO2, and HTO3 versus HTO4, HTO5, and HTO6.

Project description:We used CITE-seq (10x Gemoics-based) to profile and compare the transcriptomes and cell surface expression of a set of immune markers of naïve brain myeloid cells from wild type C57Bl/6 mice to brain metastasis-associated myeloid cells (Br.MAM) from C57Bl/6 mice bearing E0771 brain metastases. In each sequencing round, we sequenced a total of four different mouse brains (2 naive and 2 metastasis-burdened). We created an antibody pool consisting of 6 different antibodies (CD45, CD25, CD3, CD4, CD11b, and CD86) and stained each brain individually with this antibody pool. Then, we stained each brain with it's own unique hashing antibody so that we could subsequently pool the samples for loading onto the 10x Chromium and later prepare one library consisting of all six samples and finally separate each sample in silico by it's unique hashing antibody.

Comparison of different hashing methods on human PBMCs and primary mice tissues

Project description:the aim 1 was to evaluate hashing (sample multiplexing) accuracy of TotalSeq-B antibodies and CellPlex (a multiplexing solution from 10x Genomics) on 2 pools of PBMCs from 3 different donors. Thus the genetic difference between donors was used as a ground truth for sample demultiplexing based on antibody or lipid hashing hashing. the aim 2 was to evaluate TotalSeq antibody and lipid hashing on different mice primary tissues using different hashing protocols.

Single cell RNA seq of Cell Multiplexing Oligo, pooled Pleurodeles waltl and Notophthalmus viridescens spleens

Project description:The goal of this study was to test if lipid-based cell hashing worked in salamander species and to test how lipid-based hashing compared to demultiplexing samples based on species origin and single nucleotide polymorphisms (SNP). Spleens were taken from four animals in total: one adult Pleurodeles waltl (female, 23.5grams and 16.1cm snout-to-tail, strain: tgSceI(CAG:loxP-GFP-loxP-Cherry)Simon), one adult Pleurodeles waltl (male, 13.95g and 15.7cm, tgSceI(CAG:loxP-GFP-loxP-Cherry)Simon), one adult Notophthalmus (female, 4.45g and 10.6cm, WT), and one adult Notophthalmus (male, 3.55g and 10.2cm, WT). Samples were stained with CM304 (Pleurodeles female), CMO305 (Pleurodeles male), and CMO306 (pool of both Notophthalmus samples) as per 10x Genomics 3’ Cellplex labeling protocol (Demonstrated Protocol, CG000391). These samples were processed through the 10x Controller and with Cellranger 7.0 using a dual species reference. The sample origin was determined by lipid-based hashing and then compared to mapping rates to each species transcriptome and using SNP-based demultiplexing.

Multi-modal single cell analysis reveals gut microbiota reshapes brain immune landscape in aged mouse model

Project description:We used CITE-seq (10x Gemoics-based) to profile and compare the transcriptomes and cell surface expression of a set of immune markers of naïve brain myeloid cells from young-adult (12 weeks old) wild type C57Bl/6 mice, aged (72 weeks old) wild type C57Bl/6 mice and young-adult and aged C57Bl/6 mice with antibiotics induced gut microbiota depletion. In one sequencing round, we sequenced a total of 12 different mouse brains (3 young control, 3 aged control, 3 young depleted gut microbiota (ABX) and 3 aged depleted gut microbiota (ABX)). We created an antibody pool consisting of 31 different antibodies (CCR2/CD192, C117/c-kit, CD11b, CD11c, CD172a/SIRPα, CD25, CD3, CD38, CD4, CD44, CD45, CD45R/B220, CD86, CD8a, CD90.1, Cx3cr1, F4/80, I-A/I-E, Ly6C, Ly6G, NK1.1, PD-1, PD-L1, CD169/Siglec-1, Siglec-H, TMEM119, XCR1, CD24, CD103, CD64, CD83) and stained each brain individually with this antibody pool. Then, we stained each brain with it's own unique hashing antibody so that we could subsequently pool the samples for loading onto the 10x Chromium. Young Control and Young ABX brains were tagged with HTOs 1-6 (HTO 1-3 for young control and HTO 4-6 for young ABX). Aged control and Aged ABX brains were tagged with HTOs 1-6 (HTO 1-3 for aged control and HTO 4-6 for aged ABX). Young and aged were loaded in separate wells on the 10X Chromium. The samples were tagged with unique nextera index primers to allow for preparation of one sequencing library consisting of all 12 samples and were separated in silico by it's unique hashing antibody and nextera index barcode combinations.
