Lymphoid organ weights and cellular subsets of BXSB TCRα^−/− mice^a

TCRα	Spleen Weight	LN Weight	CD4⁺ Subset		CD8⁺ Subset		CD19⁺	PBMC Mac-1⁺
TCRα	Spleen Weight	LN Weight	Total	CD44^high	Total	CD44^high	CD19⁺	PBMC Mac-1⁺
−/−	0.2 ± 0.5^b	0.04 ± 0.01^b	1.2 ± 0.05		0.8 ± 0.01		85.5 ± 0.9^b	8.9 ± 0.1^b
+/+	0.4 ± 0.05	0.4 ± 0.02	17.7 ± 1.5	84.9 ± 2.7	2.3 ± 0.3	81.2 ± 2.7	74.9 ± 1.4	21.2 ± 3.2

a CD4⁺, CD8⁺, and CD19⁺ are expressed as percentage of total splenocytes, CD44^high as percentage of splenic CD4⁺ or CD8⁺ cells, and Mac-1⁺ as percentage of PBMC. LN (axillary, inguinal, cervical, and mesenteric) and spleen weights are in grams. Values are means ± SEM of six to eight mice per group at 5 mo.
b , p < 0.05 between knockout and WT mice.
